|This guy makes me laugh.|
Z (from the kitchen): Do you want water or anything?
Me: I would love some cranberry juice.
Z hands me a glass that I had been drinking water from earlier, now filled with cranberry juice.
Me: Did you rinse the glass before you filled it again? I noticed some stuff in the bottom before.
Z (got a weird look on his face): Of course I rinsed it. Wait (grabs glass out of my hands) what kind of stuff?
Me: Just dust or something.
Z: Oh I thought you meant you were clipping your nails and put them in your glass or something....
....I have no words and am pretty grossed out he would think that is anything I would do.
