So, me and this girl decided to meet up on Saturday. She said she works on Sat also, but will be free later at night and will know exactly when the same day. I said that's fine with me.

So, it's Saturday. I texted her, at 1pm, "What time at night you free?". She didn't reply for 3.5 hours now.

I know she will reply in couple of hours most likely, but should I punish this behavior and tell her I have already planned other things (I actually do), when she replies?

P.S.

For "Always text for logistics" aspergs: If I would have texted her "10pm at X", there would be a high chance I would go and she didn't show up, correct? So always text for logistics ain't so good after all.
