[EX Q]: I carefully read the book Overthinking and learned a lot from it. Which is playing an important role in my real life. Moreover, with this I have been able to change my self-esteem and mental attitude to success. The book changed my life. Thanks to the author.
[EX A]: positive

[EX Q]: The socks are fine for the price, but it would be nice if I actually received a 12 pack. I received an 11 pack and one single sock with no match ☹️. Booo.
[EX A]: negative

[EX Q]: To say this is coast guard approved is misleading at best. Pay attention to what I say next: you are required to have flares and this is not a substitute!! How do I know...the coast guard told me so--- two stations on long island. This is made to go on a life vest and is just an extra layer of insurance. Flares must be on board and not expired.
[EX A]:
negative
