I just recently moved into a roommate situation after being on my own with just my dog for the past two years. My roommate is actually someone I roomed with several years ago so know her quirks and she knows mine. Still, it's a change when you're older and been alone for awhile. Before this my roomies were my son and two of his friends, exJW twins who were forsaken by their JW parents and family. They just called me 'mom'. As for temp settings...ahem...I like it cool with the window cracked in the winter. My roommate likes the heat on.
You sound like a great roommate, Terry!
