I use these things to clean my glasses:
I keep an absurd supply of them in my pocketbook
whenever I open my pocketbook they have a tendency to fall out and land on the floor.
Whenever this happens I always feel the need to hold them up and announce to everyone in the room, I use them to clean my glasses!
Because I think if someone were to look quick at these packets they might mistake them for condoms.
I just want to make it clear to everyone in the room that I am over prepared to clean my glasses not over prepared for something else...
