Posting on amirite.
Holding a door? I don't consider that a good deed. It's just being polite. Changing someone's tire is more in line as a good deed. But that's just my humble opinion. :)
Oh I always let people go ahead of me in line, especially if they have one item & I have a cart full of stuff.
Now that's a serious good deed! :)
Stopping for a driver, so they can drive to where they need to go.
Sharing my pizza.
Yesterday I waited with our local blind lady and helped her get across a busy street. Her guide dog was skittish so she was happy to have the help.
I often hold the door for people, its just the polite thing to do.
