Given the task definition and input, reply with output. Craft one correct answer to the question given in input. To make it more interesting, try to use non-stereotypical language if possible. Make sure your correct answer is reasonably long, consistent with the context, and requires common sense (instead of explicit extraction from the context.) In your answer, use as few words as possible from the given context. Use a response that is uncommon/non-stereotypical, so that it is less predictable. To be less repetitive, please vary your language for each question.

Context: So on the train we went - seeing the dinosaurs and stuff we had n't seen on our first day . I admit , I welled up a few times during the fireworks and on that train ride . Both for memories I have from my trip with my dad ( recently passed ) and memories we were making with our girls on this trip . A very , very special place Disneyland is .
Question: What are the reasons I " well up " on the train ?
I remember my past and present visits to Disney and it makes me sad , but grateful .
