I got a haircut at a party once, many years ago.
me: "man, I need a haircut"
some guy: "I’ll cut your hair."
me: "really? You know how to cut hair?"
sg: “yeah, sure, sit down, somebody give me a scissors.”
<five minutes later>
sg: "oops"
me: "what? You said ‘oops!’"
sg: "I’m not sure what to do now!"
me: "you said you knew how to cut hair!"
sg: “yeah, but I always wanted to try it, and if I said I didn’t know how, you wouldn’t have let me.”
I started to get upset but then I remembered that was exactly how I learned to ride motorcycles. So kind of a great wheel of karma thing.
