while we're at it, here's an oldie but goodie. we've all had a drink out of a carton - you may live alone, it may be the last sip - totally legit in my view. but drinking from the company-supplied milk & OJ at work, from the common fridge? and putting it back in plain view?
there is a website dedicated to these - good for a laugh: http://www.passiveaggressivenotes.com/
on a more postive tone, i didn't get a snap fast enough, but the sign on the fridge on our new floor read, 'let's not fight over the fridge, let's hug it out'.
