Sounds like you’re trying to “drop” Grandma and get your inheritance sooner.

Wow! I wonder what would happen if you dropped a fifty in her house.

Why would you even have your grandma bend over to pick up anything when you are there? You should be picking up stuff for her whenever you can.

My interpretation was he/she wanted their grandma to find it later, and possibly think it was hers that she lost and keep it. A lot of elderly people won't ask for help because they get embarrassed admitting they need hand outs, this is a win win for all! Well, theoretically it was...

Why not just "give" the 20 to her?

A lot of people won't accept money, especially from children/grandchildren

kitchen counter, bathroom sink, dresser, pocket of her fav sweater ... don't EVER leave something on the floor for anyone over the age of 75 to pick up. Now you know why.

As a firm believer in Karma, you grandmother must be a cunt.
