I've never seen anyone wear a blazer or suit that bad. Way too short, way too tight, and for crying out loud he's wearing his tie on the outside of a buttoned jacket without his collar buttoned.
I've never before seen someone say You're instead of Your. It's always the other way around because people are just too damn lazy or stupid or both. So it takes a special kind of stupid to actually mess it up the other way.
I do it sometimes but it's only when I'm not paying attention and accidentally type the wrong one. I know the difference but I don't always proofread. If I have typed one version a lot just before, then I will often type that same version out of habit.
