why?!

why does everything i do have to come back and bite me in the ass...
for instance, i stop talking to a particular person, who happens to be working as a temp at a bank, because she is annoying....

now, summer is here and im want to get a summer job, and my sister suggests asking her, to try my luck and tells my mom about it, and then my mom starts on my case about how i didnt think about it and how im not concerned and shit....

oh wells....thats life for me i guess
