I Love the Banjo.
I can play a lot of instruments in a very basic way, so learning the banjo was not a horrible task.
I borrowed one from a friend to use in a year 12 theatre studies performance exam. I had it at my house for a week, and I loved it. A year went by until I bought my own, and I've been slowly learning to play it properly.
When I am feeling sad sometimes it works just to pick up the banjo and pluck for a while. I think "I am playing the banjo!" and that can be enough to cheer me up sometimes.
