sensitive

i bumped into a friend on the street the other day and started chatting about how much the weather has been affecting my mood. he said, "sounds like you have s.a.d." i had heard of seasonal affective disorder but i didn't know about the funny acronym. while i believe that there is a tendency to over diagnose things in this country and give every miniscule behavior/thought/tendency a name which includes the word "disorder" in its title, i do think my mood shifts with the seasons. but i think it shifts with any and all of my surroundings (i believe this is true in part, for most people).
today - for example: i was out in the rain at 6:30am to volunteer for a NYRR race. not because i have a big heart (although i do) but as a requirement. it was an all women race, and about 10,000 women showed up (despite the awful weather). some women were super nice and appreciative that us volunteers were standing out in the rain for them (this made me feel nice) and other runners were super aggressive, obnoxious and rude (ok, maybe one in particular) but it set me off in the worst/angry mood.
i tend to have the same sensitivity when driving. if i am in vermont, i find driving to be a pleasure, a calming experience, like i'm one with mother nature (while simultaneously destroying her...). but in the city, it is not only NOT "calming" but i develop the nastiest road rage and become a super asshole.
i feel like a chameleon.
