I don't know if this falls into the category of OCD EXACTLY . . but I find it hard to part with things, purely physical THINGS without some sort of goodbye.
Case in point, today at work, I took my 2005 calendar down to hang up my new 2006 Lighthouse calendar (that I snagged for $1 at Target!). I felt bad simply tossing the old calendar in the trash. I had to kind of hold it for a moment and then give it a kiss before throwing it away.
Get that look off of your face. I know that's not normal.
Happy New Year.
