My mailman is hella chill. It's the typical small town thing, really - he knows I schedule pickups on days I don't work my "main job" until late, so when he comes really early in the AM he pounds on the door and wakes my ass up. I proceed to roll out of bed in my PJs, hand him my shit, and then crawl back to bed until my alarm goes off.
That being said, I wear a lot of muscle tanks to bed and the dude's cool but not "accidentally flash him a boob because I don't realize it's hanging out of my top and then never schedule a pickup ever again out of embarrassment" cool.
Check yoself before you wreck yoself.
