Ok, this might sound a bit weird, but I hope not..
Do you know the smell (or at least the nasal sensation) you get when you walk outside in the winter? It feels cold, crisp, & awesome?
It may be that I just walked out of the shower..
It may be that we just got over one of the nastiest humid heatwaves in memory..
It may be that humidity is unusually low right now..
It may be the violent thunderstorm last night "cleaned" the air..
I don't know what it was, but when I opened my window and stuck my nose out, it "smelled" like winter. And it was awesome.
hopefully I'm making sense...
