I have to wear socks to bed no matter how warm it is. Without the socks it feels like my toes are wild and unrestrained, they might just run off in the middle of the night. The socks keep them where they belong.
In the same way I can't stand for Ben's toes to touch me. It doesn't matter if they are in a sock or not - there is something weird about the feeling of toes touching me.
What is a random fact about you?
