We were at a large, busy play area, when I found a little boy (aged about 3)crying that he was lost, and couldn't see his daddy (it was fine, his dad was there within a minute). I was reassuring him, and telling him that it would be ok, we would find his daddy. But I was surprised to find myself welling up, and having to make a real effort to keep it together. Is that a normal response, or am I just over emotional?
