I work in a friendly office and have a good relationship with my line managers. My boss's boss is a pleasant person who has other colleagues as FB friends so I thought I would send her a friend request. It was almost immediately rejected and now I feel mortified, especially as she's someone whom I wish to impress. I obviously misread the signals in thinking she wanted an informal friendship (she greets with a hug, is complimentary about my work etc etc). I basically feel as if I've been rejected by the cool kids. Should I apologise, ignore, what? I'm massively overthinking this but I feel I've made a massive tit of myself and don't know what to do next time I see her.
