I never understood the word selfie when it comes to more than one person. Once someone else is in, it's no longer just yourself. When it's more than one, shouldn't it be called an "us-ie"?
Well, setting her alight seems slightly over the top even if she is a "selfie taker". Hard to argue against a good punch in the face if she is, though...
1. Wrong use of "your". The correct use is "you're".
2. I don't know why I got down-voted. I'm from the US, and not of legal age. I was saying, if I was 21+ I would have bought OP's dad a case of beer for his comment.
You got downvoted because people didn't like your comment, so quit whining about it. There's nothing more annoying when people try to defend themselves after having a comment downvoted. Also, 49 didn't even say "your", he said "you're". So, the only real mistake he made was leaving out the apostrophe, which was likely only a typing error.
