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 ?
Options: 
- I remember my past and present visits to Disney and it makes me sad , but grateful .
 - None of the above choices .
 - I am upset because the baby is crying with me on the train .
 - I had dirt in my eye .
