If he's drooling over her body for 10 mins prior to speaking up, chances are she noticed his glances and body language and was just waiting for a signal to flee, but was giving him the benefit of the doubt.

shit . the ogre speaks .

I often chat with people in saunas and they dont care, if anything its usually recieved positively but knowing this is 4chan anon is probably failing to mention some crucial details that would draw a more complete picture.

The sauna always has the weirdest creatures.
