Sometimes I crack myself up with how silly I am.....
made an egg and toast sandwich.
cut a slice of cheese to grate onto it. grated about 3/4 of it, put the rest on the counter.
looked at cheese while assembling sandwich.
came back later, realized I had purposely walked away from cheese in order for it to harden, thereby making it inedible, so I would have an excuse to throw it away and not eat it.
