I don't think I understood a WORD of that, O.T. You drinkin' again today??
But boundaries DO need to be communicated. Other than the "enforcing" of them, the "communicating" of them is pretty much the most important part. Hell, maybe even MORE important.
CAN they be uncommunicated? Sure. "Man, the FIRST time this new girlfriend of mine pulls out lipstick and starts applying it in front of me, IN PUBLIC, I'm outta here . . . " Or maybe an off-color ethnic joke might be another example -- you don't need to tell people ahead of time that you find it tasteless, but once they say it in your presence? Then damn right you have to communicate your boundary.
