My son is now a very good reader, so he can read the signs these people have. He saw one today that said "Help a vet, please help." My son starts pleading with me to stop and help this man (he is a very tenderhearted little fellow). I try to explain in first grader terms that if I had food or something I'd give it, but I NEVER give money. That is my rule. I then tried to reason with my son about how people can always find a job. Even if you had to work at McDonalds.
My son then looked at me and said ,"Mom he doesn't WANT to work at McDonalds. He wants to be a Vet."
