It would sound pretty ridiculous if I asked someone to "countertop me a sandwich"
It's equally as ridiculous when someone asks us to "inbox me."
There is no way for me to do that, that's not an action. I can no more "inbox" someone than I can "jigsaw puzzle" them.
Now if you'll excuse me I'll get off this soapbox I've been velociraptor on.
