I think you can tell something about people from their choice of bedsheets.
So - what do you slip your tired body between? Egyptian cotton with the highest thread count? Good old fashioned flanelette? Those 70's porn-style fake-satin sheets? Scratchy slippery nylon? Or don't you care two hoots so long as they're clean?
(Mine are highest quality cotton. And white. With a bit of lacy or fancy edging) That is because I am a very pure high quality person who likes the odd bit of frippery ..... :-)
