If he's sat down he leans his elbows on the desk and holds his pen with both hands. He holds it by each end and twirls it back and forth while holding very strong eye contact.
Really creepy! I can't describe it well, but honestly, it's creepy!
If he's speaking to me standing up he always strokes his I.D badge( not a euphemism thankfully) or fiddled with the buttons on his shirt while maintaining an almost surprised look on his face/strong eye contact.
He's done these exact mannerisms every time he's spoken to me since I started 6 months ago. I've noticed I'm the only one he does this with.
Is he a serial killer? Shall I change jobs?
AIBU to be a little creeped out or am I being completely absurd and deluded and this is normal behaviour on his part?
