"Bandaids don't fix bullet holes, they say sorry just for show" -Taylor Swift
This is correct both metaphorically and literally. Bandaids can't actually fix bullet holes, but that is not the meaning of that lyric. The true meaning is that you can't take back words you have already said. In other words, the damage has been done, and just a little 'sorry' won't fix things.
I was just thinking about that, and I decided, why not make a post? Have a good day!
