Little Neophyte -

I know just how you feel. First of all, you are to be congratulated for having the sensitivity to see a situation as inapropriate for playing your music. Not everyone has that. Secondly, yes, there's alot to be said for leaving your instrument for a short while and coming back to it. It can and sometimes does play a positive role in one's musical development. I have found myself more relaxed and fresh coming back to it, and have found that I could play it with an improved technique that I couldn't do before. It's very much like a human relationship, too, for the reason you gave.
