Maybe send an email or post on facebook? I know some of my friends didn't get it especially when all three were in the scn that you can't just rock up and have cuddles.
It's more the older family members I'm worried about, like Scott's dad (who I really hope doesn't visit, but probably will) and assorted auntie/uncles. So I can't do it like that They'll probably ignore it anyway, I'm just the silly girl with all the big ideas about how to live in the world...
