I was recently speaking with my father who reminded me that from the time I was about 5 to the time I was 13 I spent approx 250 - 350 hours working with disabled children in Mexico. He thinks I should add it to my app under activities, while I think it's too unprofessional and should be mentioned maybe in my CV or my PS. Someone please reassure me that I'm not being an idiot by choosing not to put this in my actual activities.
