Another One

I don't know what it is about what I say, or the way I say things that people so regularly choose to take what I say (or more likely - write) in a bad way. Friends have fun with each other. They tease each other. Not in a nasty way, but in an affectionate way. So why, when I feel I have a friend and I say something playful to them, do they choose to hear what I say as mean?

for god's sake
