I work in a small department of 8 people. Our head of department has a party in July for her birthday. Invitations were given out today. However, only two people in the department for invited (not including me)! Until recently, I was her second in department and I thought, friend, but clearly I was wrong. I know it's her party, she can invite who she wants etc but really? Only invite 2 people from your department? AIBU and do I just need to get a grip?
