i hate it when i'm second guessing myself all the time. i always end any argument i have with anyone with "but i could be wrong" i guess that defeats the purpose and i get to feeling depressed too...
i think youre right, i think it is a reaction to the harmony being disturbed... perhaps it was just your moods, hard to say w/o seeing or knowing what the argument was about to begin with, not that i'm asking you to share... although you can if you want.
