Oh, & someone mentioned writing on paper. I get TOTALLY nuts over writing on paper. If I make a mistake, I throw the paper out & start all over (even if it's just a grocery list). Same if my pen runs out of ink & I have to switch pens. I won't use paper is there's something on the other side of it. I use a piece of lined paper inside an envelope when I address it so my writing on the envelope is straight.
The more I read of this post (& agree with pretty much everyone says... I'm the same about the sheet/blanket dilemma tho I go one step further... my top sheet has to be put on print side down so when I fold the sheet back over the quilt, the print shows & not the wrong side), the weirder I think I am. DH has always commented (not negatively, just observing) on all my weird habits & I think I finally see that I'm not normal... LOL!
And don't even get me started on all the weird things I do when I eat (but unlike someone else on this thread, I have to eat my corn around instead of long)!
