What a sad thing; I can imagine being a college student, finally doing well in school and proud of the accomplishment, calling Mom and asking if I could come for a visit - and being told she'd have to think about it. As a matter of fact, I might have assumed that I was welcomed...glad your D had the foresight to check first. What a welcome home that would have been! REWARD good behavior, dumba$$!!!!
Sorry....
as for S crying....my S was always sensitive, would cry a lot. I remember getting worried about him, just around your son's age. Would he always be like this? Would kids start calling him a crybaby? His dad would get angry at the tears... I have to say, he has grown out of it for the most part. Recently, probably over last year and this. I hadn't even thought about it until just now...now, he seems to cry over things that are really sad, rather than frustration. I just kept up with him, telling him to use words and other ways to express himself when he was frustrated, disappointed, angry...and pointed out when tears were appropriate because of sadness. (Unfortunately, he had a lot of practice in experiencing the difference).
