It did not, it's just that sarcasm/irony is common on the internet, and tone is hard to convey just from written text. I was not offended at all, but thanks for being a nice person on the internet and apologizing anyways!
Often when I try to copy other people's facial expressions, I realise I have no control over my facial muscles if I try to move just the left or right side. It's absolutely fine if I move both sides at once but I literally can't even sense the muscle to move it when I try one side, but my friends can. I can wink though, but I used to do it very unnaturally.
