I must be paranoid to some extent because I have namechanged and also I will change some details in this post (not the important ones).
I teach music at my home. One of my friend's husband wants to start learning an instrument. I said fine, but didn't hear anything for a while.
Today when I was picking up my dcs from their house, he brought it up. He just seemed really weird though. Saying stuff like, I'll come round one evening and we can 'mess around'. I just took it that he meant 'mess around on the instrument' (although that seems a weird thing to say). He also said one or two other things that I thought could be taken the wrong way, and he sort of raised his eyebrows in a way that I can't really describe.
Anyway, AIBU to be a bit concerned? I can't refuse him lessons (I get on really well with his DW and dds). Should I ask a friend to come for the first lesson as a sort of chaperone? Should I hide the friend upstairs?
Am I being paranoid? (disclaimer - I have an excuse if I am, due to my history)
Oh by the way, I am a single mum.
