I can’t think of anything more perfect than something that you thought was gone returning.
When you sense someone might be about to mug you, mug them first: Don’t be afraid to take action. If someone seems like they might be following you, pull a gun on that person and steal their valuables. This will send a clear message to the potential mugger and decrease your chances of getting mugged.
If you can’t do anything about it, laugh like hell.
Books. People have no idea how beautiful books are. How they taste on your fingers. How bright everything is when you light it with words.
