Charlie Brown

How can I ask my wife to stop using my childhood Charlie Brown glass without seeming like a wuss?
We recently moved and in doing so, I found buried in an old box my childhood Charlie Brown glass. I have very little from my childhood and sometimes — OK often — enjoy drinking from it.
Anyway, I notice that my wife grabs this glass first thing in the morning and starts using it. She doesn’t have a childhood glass. I’m afraid she’ll break it, as she’s a klutz.
Get her a Lucy one and tell her that’s hers and Charlie Brown is yours, like his and her glasses. You should be able to have something that is exclusively yours, especially something that’s from your childhood. Better buy her a couple of the Lucy ones so she has a backup one in case of an accident.
