I just called my mother at work, who answers her phone about 100% of the time...
And since it is a direct line, it doesn't bother either of us if and when I get the urge to call her while I'm doing things like brushing my teeth, eating, driving...or peeing.
So, I'm doing the last one on that list...and ya know...I've had like a liter of water...as soon as I begin, a coworker picks up her phone and says, "Toni's desk..."

"Oh...um...wow, this is awkward. You can tell I'm peeing can't you."
"Okay, yeah, I'll try her on her cell, thanks"

is there such a thing as being too comfortable?
I wonder if it's just me.

oh well.
