This is a bit of a weird one - so I popped home today unexpectedly while the nanny was in my house with the kids. Everything seemed fine, but then when she was talking to me I looked down and saw that she was wearing my slippers. It made me feel sick. They're not the cleanest or newest of slippers, but I didn't know what to say. I don't know if she's been doing this the whole time or what but I feel like binning the slippers and hiding my slippers in future. I also feel like letting her go over it. It just makes me wonder what else she might do when I'm not there. She's from Brazil. Is this normal in Brazil to just wear someone else's slippers? Am I being weird to have a total icky feeling about this?
