We've been learning that bad grammar is the worst enemy of the tattoo artist. You'd think that because they have to write so slow that they'd catch their mistakes, but that doesn't seem to be the case. This is an especially infuriating case of bad grammar because they somehow used the same word incorrectly twice but in two different ways. The first "your" should be "you're," short for "you are." The second "your" should just be "you." It's like this tattoo artist was going for a world record.
A lot of people mess up their "yours." It's as common as screwing up "there, their, and they're." Not many people, however, screw up "you." That one is usually pretty easy. This is why 18 is too young to be able to get a tattoo without an English teacher's written consent.
