When Tina was living with us we were at church one Sunday and she leaned up and looked over at me and made a motion with her finger under her nose inferring I had a booger under my nose I needed to take care of! I was very embarrassed but grateful she was letting me know this so I proceeded to wipe my nose. I looked over at her and she made the same motion with her finger under her nose again so I obviously hadn't gotten the job done and needed to try again! I wiped again and again over and over until my nose was almost a bloody stump only to realize there was really nothing there at all!!! Oh my I had to go out on the hall when I realized what she was doing cause I was laughing so hard and being irreverent!! Still laugh when I think of that. Sad thing is I fell for the same trick from her later.
