Reminds me of when I play my mandolin when I’m camping. I’m sure fellow campers think I suck, despite having played for ten years. But I’m not going to play stuff I can play in my sleep, I’m playing stuff that still needs work. So, in consideration of others, once in a while I’ll rip off a fast version of Old Dangerfield or some other song I know really well just in case someone is in earshot.
Why do you think other people want to hear you practicing songs that you're not good at? I'm imagining someone trying to learn the recorder by the campfire.
