I've got two that are really bothering me today:
1) Friends I went to HS with posting statuses like "I'll be in X city on X day, who wants to let me crash on their couch?" RUDE! Furthermore, you're an adult; don't plan a trip when you can't afford to put yourself up unless someone OFFERS first.
2) My old boss just got fired Friday. She sent me an inappropriate FB message wishing me "good luck" when I go back next month because they're all idiots over there now because they fired her. Now her FB statuses are all about how she's glad she got fired and her current employer is now "No Longer working for ASSHOLES!!!" That's real professional, lady, and it's sure to get your hired again soon.
PS: That work thing is such drama I can't even get into it, but the store is divided in halves, people are evidently planning on leaving and some told me I shouldn't go back -but hey, that means more hours for me! She wasn't very good at her job to begin with.
