When you get really drunk and order a pizza online after the store has closed. You forget that you ordered a pizza because you were drunk and there is a pizza in the stores queue in the morning. They proceed to deliver the pizza when they reopen in the morning. You hear a knock on your door while you are sleeping and in the doorway stands the pizza man who just served as your alarm clock.

When the “crush” has no intentions of taking things further, but they like the attention. So they flirt here or there, send dm/texts just to keep the person interested, knowing damn well they’re staying single.
