Yes, I did see the 'lol', but it seemed like a sarcastic one at the time of reading (somewhere around 1:30 AM), so I - of course - responded in kind, which only goes to show that I shouldn't touch these things at those hours. >.<
But yeah, sorry; I didn't intend for it to come out as rude as it did; the late posting time and the fact that I had - after loudly and frequently declaring my absence everywhere I could think of for about half a week - come back to x amount of messages complaining about why I hadn't been around just kind of got to me. :\
