We're veering extremely off topic, but I don't think you're aware and maybe you should be: my antagonistic attitude is 100% a reaction to you being overly friendly. Calling me your "friend" repeatedly without any prior acquaintance comes across as remarkably sarcastic and condescending. The "So what? :)" wasn't any less condescending either as you may imagine, in fact, quite the opposite.

I'm sure there are people who can always reliably respond with kindness despite being handed condescension. As you can probably tell by now, I'm not one of those.
