There was a time when I was very young that I accidentally threw out my retainer, which is a plastic and metal thing that you put in your mouth after having braces for many years, and these things are really expensive for god knows why. Well my family and I spent hours going through the dumpster of I think it was an Arby's and man that was not a fun thing. In the end we didn't find it and I had to get a new one. I was in pretty big trouble that day because my family is not wealthy and this was hundreds of dollars.
