I need a hobby

I need a hobby. This realization have hit me before, but having a little extra time on my hands (without access to my usual distractions) have put the topic into focus over here. Without one, I'll end up either working too much or with serious TV withdrawals around Christmas. So far I've mainly entertained myself by walking around and discovering the area, which is fun but also starting to wear on me. Today started out quite cold, or what would be described as chilly with a high humidity in northern Europe. Imagine an early fishing trip in the mountains the morning after a rainy night and you'll get the idea. Anyway, seizing the opportunity to wear my incredibly nerdy hoodie in public, I did what I've done quite a few times now and took a stroll around town. The local Brazilian sandwich stand celebrated its ten-year anniversary with a street party. The Hawaiian BBQ joint grilled me some mightily good sesame seed bagels. Staples (a chain of office and school supply stores) sold me some headphones. And after lunch the sun came out, like clockwork, and scorched me to the point of going back indoors again. After picking up yet another box of fresh strawberries of course. It was a great day, but the rest of it has been spent reading and watching TV. I need a hobby. Any suggestions?
