one trouble of not having a boyfriend

i think it would be very funny to note what happened today:
i was talking to a friend/co-worker after hours today in an imaging room, which had minimal red lighting. this friend/co-worker is a physical therapist besides being a research scientist and a lecturer. as we were talking/hanging out, i requested a therapy (massage) for my chronic shoulder pain. all of a sudden, our boss walked in, which wasn't a problem except he looked at us funny and said "what are you guys doing?".

to make things worse, this was the 2nd time it happened. however the first time was at a different lab room where we both worked on the microscope all day counting cells and we exchanged backrubs right there in the public.

it was so weird that he looked at us like that, but what should be done? it's okay for the friend as she's leaving soon, but i am staying for a while longer. i can just imagine what's going on in his mind...

this is funny, and a bit troublesome...but it should make a good joke no matter what.
