UM, it is because there is a streak on invincibility in you!!! So take a hint you are not meant to be cut or scarred!!!
Or the angels, spirits, gods watching over you do not want you cut/scarred, so maybe give them a bit of a rest it's got to be tough being an angel, spirit or god sometimes!!!
Or you've inadvertently come into contact with whatever Superman did so why/how could you defy what is meant to be!!!
Now aren't those excellent reasons why YOU are not a failure and why you should try to give yourself a break??? Those and WE LOVE YOU!!
Now no arguing!!!
