It's a good day for this one.
Comfort beverage: Hot. If I'm home, usually tea. If I'm out, usually coffee/latte. Hot cider (no caramel!) is very good when it's in season.
Comfort chair: Usually not so much a chair as a couch. Up here I like my green loveseat with my throw blanket to curl up in.
Comfort read: Little Women. Occasionally a Madeleine L'Engle novel for a change, but mostly Little Women.
Comfort television/DVD/music: TV: West Wing. DVD: Kissing Jessica Stein. Music: I keep a sad songs playlist for just such occasions - mostly composed of Indigo Girls, Dar Williams, etc.
Comfort companion(s): I have no lovers or pets (ok, I have a fish, but that hardly counts here). I guess my comfort companions would be certain friends who know me well and who don't mind when I need to be silent and/or sad for a while. Or, in a pinch, my Care Bears.
Interesting that comfort food is not listed.
