A fun look at the family of "streichen" and what painting your wall has to do with emphasis, petting your cat and pranks.
streichen, durchstreichen, der Strich, der Aufstrich, der Abstrich, streicheln, der Streich
The core idea of this root was:
This would mean that besides streichen, also Strahl (ray), streifen (strip) and streuen (strew) would be part of this family, but the English sources I have seen do not mention this at all.
English family members are definitely related are strike, stroke, stripe and streak.
