I'm out of the office until Tuesday 12th October 2021

 What's a nice person like you doing looking for a person who isn't here like me?

If you need any more catchy out-of-office-themed pickup lines, either wait till I return on 12th October, or contact Jo, who will probably tell you not to encourage me.

I'm out of the office until Friday 29th September 2021

 I was intending to avoid writing an out of office reply, but as you can see, I've failed.

If you need anything while I'm away, you can contact Jo.
