Exactly, NOT mad, hurt etc etc. JUST busy, preoccupied with your rehearsal or something else.
I wouldnt hide. No. YOU have no reason to hide. Remember, this is YOUR house and for now, he is a "visitor". You own the place, you are in your territory, dont fret, walk around like the cat that just ate the bird (do you guys have that saying?). Dont overreact, if he starts a convo, asnwer with something that needs no further discussion. If you can squeeze in a smile, that's fine, if not, just keep calm. Good luck K
