Seperation of Church and State

What about seperation of work and play? I'm starting to get weirded out by people asking where I was after work or on days off like I've done something wrong by going out and about. I was asked by my boss today if I had gone to the bar the night before. I had in fact gone home after work and fallen asleep quite quickly due to exhaustion. I was then asked if I'd gone out the night before last. Instead of asking why I was being grilled I just said yes that I'd gone out for a few beers with some friends. Truth be told though, I'm annoyed at myself for answering. What I do in my time outside of work is really my business. But since I'm really a rather boring story I might as well just lay it out even though it's boring:

Sometimes I go out to a bar and drink beer with my friends. Sometimes I sit in my room and play my guitar for hours. Sometimes I sit in my room with my friends and drink beer and play my guitar for hours. Sometimes I clean my room, sometimes I do puzzles, sometimes I lay in the park sleeping and soaking up the sunshine, most days I go to the gym and sweat like crazy, some days I read and write and sing along to music too loudly.

I told you it was boring. Really...Who cares? I have nothing to hide. I'm really a rather humdrum kinda gal.
