I was going to express flabbergastation (that's a word; I invented it over 10 years ago on Cheezburger) that you only have one mouse that both your computers have to share.
My computer at work is a desktop that has its own, wired mouse, but sometimes I bring my main laptop to work so that I can work on both computers simultaneously. Sometimes I am watching a video on one while typing on the other, or attending a remote event on one while typing notes or a document on the other... things like that. I have a wireless mouse for my laptop, and when I left work I just forgot my wireless mouse
But it seems that you left your favorite mouse, but you still have a spare.
I have multiple spares, plus I have multiple laptops, including the laptops my wife and kids use, so there is no shortage of having a mouse to use if I need it. Still, I like my regular mouse (Microsoft wireless usb). I'm using a Microsoft wired usb mouse right now. As an aside, I learned this weekend that even if you have a duplicate usb mouse, the usb wireless receiver is hard-coded to the mouse it came with, so even though I had another identical Microsoft wireless mouse at home, I couldn't use it, because the usb receiver it came with is broken, and I can't re-assign the receiver inserted in my laptop to the other mouse, despite them being the exact same brand/model. So essentially, once the usb receiver breaks, the mouse is garbage.
So I'll have to order another spare.
So you'll get your favorite back on Monday?
Yes I'm not going to drive all the way to work just to pickup my regular mouse so I'll just get it tomorrow when I return to work.
