I got the bike back to a usable state for the morning ride. Due to the walk home and the repairs I was already 45 minutes behind schedule. My son was standing waiting for me, so I chose to help him with his homework instead of tweaking the derailleur right then and there. Then supper was ready. After supper was done I had to go to the store for my wife. By the time I got home I was ready for bed.

I'll adjust the derailleur tonight. Sometimes life forces you to compromise. To me it was worth it to go a day without my granny gear because I'd made my son wait long enough. Your priorities may be different, and that's fine.
