Mine doesn't always go to the corner (that's where he usually poops). He did, started a while ago, but now, he doesn't. Sometimes he does, most of the time he just poops wherever.
The problem is, he never says he does the deed. He just does it, so there's no real way of knowing if he did poop or not, unless you smell his behind of course (which COVID made really difficult, since everything smelled like poop for me after it).
And if you ask him, sometimes you get straight answer (most of the time now to be honest), but sometimes he just likes to play and gives you a wrong one. Practically, there's no real way of knowing unless you smell him.
Kids are really confusing, you never get a straight answer about anything 🤦. You have to have like over 9000 social skills to read their reactions to the question you asked, it's really tiring if your EQ is really low and all you've ever learned about social interaction was from hanging out on the street for a very long time, but your brain is damaged regarding social skills (right hemisphere not really communicating well with the left one).
