make it shorter: 

Dear family of Cristina,
First and foremost, I must apologize for my less-than-perfect Spanish. Pero no te preocupes, I promise I’m working on it. You know, language barriers can be quite interesting, especially when it comes to matters of the heart. But lucky for me, the language of love knows no bounds, and it helped me win the heart of your amazing daughter, Cristina. 
Our love story is like a film. Two people from different corners of Europe, meeting by pure chance in the enchanting city of Prague. 
We couldn’t speak the same language, but we managed to fall in love anyway! Cristina, mi amor, you have truly transformed my life in more ways than one. Not only have you helped me shed a few bad habits (I won’t embarrass myself by listing them a front of your family), but you’ve also shown me what it means to love unconditionally. And for that, I will forever love you.
I must admit, I don’t come from a traditional family. Instead, I come with a wild bunch of brothers, my amazing group of friends who have been with me, supporting me for the good and the bad moments. So, consider this speech my way of introducing them to all of you as part of my unconventional family.
Thank you Family for welcoming me an accepting me into your lives, love you all! 

I am going to start in French for the frenchies sorry guys it’s not their fault haha we are just French haha … bon ça va la mif?   vous avez vu comment j’envoi du paté en espagnol ?!! Heureusement, j’ai pas épousé de russe hein, bon passons haha… Boooon… JE ME MARIE, les gars ! Qui aurait cru, Mike se marie… Même moi, je ne l’avais pas vu venir… Mazeltov pour moi !

Vous avez sans doute remarqué on vous a placé à des tables en fonction des pays ou j’ai vécu. Jtrouvais ça sympa.. Représentation des différentes étapes de ma vie. Bon en réalité, tout le monde est lié d’une manière ou d’une autre. Certains d’entre vous ont voyagé partout où je suis allé, donc je vous ai placés en fonction des plus grosses caisses qu’on a eu. Sans compter Aurel, Fred ou mes Reuf qui aime se mettre des races partout, donc bon euh hein haha.
Donc un gros big up aux loubards de ma région d’adoption, les « BGE style » haha et n’oublions pas le Sud-Ouest évidemment, je vis officiellement labas après tout ! haha. Se serai trop de cité ne anecdote par personne j’en ai 10 mille ! Merci de m’avoir intégré dans votre famille également , Très fièere d’être tonton mike, on verra avec les années mon bon ^^ non merci de m’avoir soutenu, aider, supporter, trimbalé, porté au fil des années. Et une mention spéciale à et mes deux Hermanos : David et Alex, sans qui je ne serais peut-être pas devenu aussi débrouillard que je le suis maintenant, Merci d’être venu d’aussi loin, je vous aime ! 

Let’s switch to English!  Next up, the Prague table!! On which I would have never ended up if Aurelien hadn’t taught me how to properly lie by memorizing a presentation in English about my fake degrees and successful professional background haha. Nine phone interviews and one in-person meeting in City’s of London later, and I was a recruiter/ Business Developper  in Prague, haha. You guys knew me at the peak of my cowboy attitude, bullshit attitude, and much more. A big Bravo to Melanie for finding out about my bullshit and leading the way and for Senior Habib for cooling me down when I was about to kill clients haha!  Big up at all you guys, love you!! 
And of course, the Portuguese table! You met me when I was very dark-haired and now almost platinum blonde. Sun, parties, surfing (well, 15 minutes, but let’s not mention that), beach, cerveja, festivals, and especially sports and almost healthy life! Thanks, guys, for pushing me all these years. I even ran a 10k race in the Czech Republic in Chep thanks to our nice Miroslav, completely drunk, but still 10k, haha, thank you all for being such nice friends too. We traveled a lot together and I hope we’ll keep doing it! They witnessed my evil plans to marry Cristina haha, since you are my most recent family, I just wish you good luck in supporting me, haha. Big Besitos amigos! 

So here’s a speech in three languages, for three bachelor parties. I wish you all an excellent time. Thank you!!!
