My new friend/acquaintance flaked on me

We made plans for 12 today, they never got back to me or answered my message. I'm not gonna take in personal or be mad at them but if I put it in the calendar and someone doesn't send me a courtesy message i think that's lame 🤷

Anyway I reacted by having a 3 hour nap 😴 and here we are. I'm probably not inviting them again, not cool.
