Parts are interchangeable?

When I went to put on my wedding band today I noticed that it was loose. At first I thought, "woohoo" I lost a little weight or something.

Hmm.

Or something. 

Because really, it was a little too loose. 

So I checked the inscription...

Yup. It read "Her Shiny".

Which means that Gregory had been wearing my ring all day.

Yeah. We're adorkable.
