Hi there and welcome to DWD. We’re all guilty of hiding away from time to time and the longer you do it the harder it is to break the habit. It’s good that you have a reason to get out a couple of times a week. The guitar work sounds interesting. What exactly do you have to do? Replace strings and tuning or something more detailed? I don’t play an instrument but I’m still a big music fan. Anyway I’ll leave you be for now, I need to find something for dinner.
