My story with mistakes like these: I am not a native English speaker but have lived in the US for about a decade. I used to feel the same about those mistakes and as someone who has learned english as a second language it was impossible for me to make such and many more similar mistakes in written english (while I was and still struggle with fluency and pronunciation). As the language became more natural to me, I started doing those mistakes myself. I think the culprit is in the way written and spoken english differ. In my native language, if I make up a word and speak it out loud to 100 people, there is a 99% chance that they all write it down exactly as I invented it. This is unthinkable in english and basically force your brain to learn two languages (spoken and written) and in spoken language "you're" and "your" are really not that different. If you write without focusing too much, you just write down spoken english. I don't know why I wrote this down! Just my experience.
