a) It's in the way the post is worded, reading comprehension. "I always have to tap out", always being a word that implies that one is doing something frequently enough that you've noticed a habit. The dude also agreed with my post and didn't reply, so I believe my inference was on the marker.
b) I said it in a joking manner because he joked about his own autism. I don't know why you're assuming that I'm mad, I'm more taken aback that my post was misinterpreted in a way that was so far off from anything I was saying.
