I have an unwanted superpower.

Invisibility comes upon me when I'm not expecting it. I'll stand in an order line only to have the server look behind me and ask the next person what they want.

Yesterday I went into the dog groomer's to ask about making an appointment for my dog. A couple brought their dog in behind me. The clerk looked right through me and asked the couple if she could help them. I blurted out YES YOU CAN, and she didn't even seem to know where the voice was coming from.

This great but unpredictable talent of invisibility comes to people over 70 like me. I'm sure it starts forming earlier and goes unappreciated for a while.
