Do you think I should worry?

Maybe it is just the holidays. Maybe it was the Tea Party Baby Shower Natalie threw for a friend today. At this point I do not know what to make of this.
While helping Natalie get the house ready for both of the above events (at the same time mind you), I found the following item in a box in the garage. I really did not think anything of it, except that while emptying the dishwasher while Natalie was out, I found the same mug, a mug she gives me almost every time she makes me tea (with lemon and honey, just the way I like it).
I will admit, sometimes I am a klutz, and will break the occasional thing, but two copies of the same stupid coffee mug? So I went back to the garage just to make sure that I was seeing the right thing, another copy of a worthless, if not meaningfully labled mug. There it was right where I left it. And then I noticed the sticker . . .

Maybe I would just let this go, except that she's been really kind of demanding recently. I'll have to find you the copy of the holiday honey-do list she left me for this weekend into next week.
