I know we all have "issuses" in our lives so thats not an excuse . I want to say this as help not to be critical. I have found some of your replies come from your heart and you mean well by them . But my mom told me something all my life, it's not what you say but how you say it. there are ways to tell some one to go to blazes and do it so they almost thank you for it.
I have found a lot of newer people have that problem so it's not just you. As a member of the older generation we were taught langauge and it useage , today the schools just don't do that. it's not the fault of the kids or teachers just so much PC (politacal correctness) and mandated junk they have to teach ( Alot that should be a parents responabilty)that real learning and socailay acceptable skills are passed by . (sorry I just will get off my soap box now.
I don't think a break is what you need but just think and read your replies a couple times put your self in the other persons place how would you feel if you got that reply. (this goes for most all of us I know I have been guilty of it too)
