Just that really!
A friend has posted a picture on Facebook of her new tattoo and there is a word spelt wrong! I won't say what for fear of outing, but it's got two extra letter in by accident 
No one has noticed that's posted on Facebook, and I've checked that it's not a prank (no google images of the same picture) so I think it's an honest mistake.
But... I can't see that me telling her would be helpful, I mean, it's permanent! There isn't a pretty way to fix it, and surely someone else will notice and tell her? Right?
I'm such a coward
