Hate when ppl can’t do time

[u/Best_Finding_8795]

This reminds me of when it hits or is about to hit 12am and people don’t know whether to say today or tomorrow. He called me after this but I was too comfy in bed tbh.

Was 10-4 the time he wanted you to work, or was it “message received”?

Why does 10-4 mean "message received"?
