A story mom thought was funny (but is probably better when told in person):

While we were at the zoo on Sunday we rented Matthew a wheelchair because his leg bothers him a lot from his surgery several years ago. We we’re getting ready to leave and as he wheeled past a group of people, one of the little boys stepped aside, patted matthew on the shoulder and said (very sympathetically) “Take care, man”.

He then proudly turned to his mom and let her know his good deed to the wheelchair man, then continued on his way.
