I try to organize my errands so I do a little each day, not too much in the way of recreational rides, so I get everything I need without needing a drive from anyone.
This week I'm trying to get my fancy clothes together for a wedding on the weekend.
Yesterday I discovered my fancy white shirt had a stain that dry cleaning and bleach wouldn't salvage so I had to head off to a department store in a nearby suburb.
I was already so tired after working all day and then of course the commute and the trip to the cleaners after dinner. I didn't want to go, but had to... Got the shirt and got home... but I was zapped.
I also have a story about getting my suit dry-cleaned, then having to bring it home in a pannier But let's save that for another thread.
You have any stories of doing errands by bike while you are tired?
