Don't ask people if they're free on a certain date without specifying why you're asking. Simply asking "are you free on Friday?" comes across like you're tricking the other person into doing whatever it is you want them to do.
If you constantly vent your problems to someone, make sure to also call them when things are going well. Good listeners can sometimes get overwhelmed, and it's nice to hear positive news. To add to that, also make sure you're available to let them vent their problems. Relationships are a two way street.
If you have a chore that you actually enjoy, never tell anyone you enjoy it.
You'll do that chore for the rest of your days, even if you stop enjoying it.
You get no credit for doing that chore, since it’s really not even a chore, right?
