Why do people tease me over undesirable things that happen?

For instance when something happens that appeals to me like having an interaction with a woman and then I inform other people about it and they're like "Don't inform us, we don't give a shit" and they become persecuted by me and back off, but when it comes to undesirable things that frustrate me and among other things , they're like "Hey, sounds like you've been bragging to all of us about your disappointments and frustrations, how about we salt up a little bit your wounds? Sounds like the stink will haunt your for the rest of your life."
