How aware are you between someone you think looks stunning vs someone you just want a convo with?

How does that and how do you generally percieve your surroundings subconcsiiusly in those situations?

If you were asked which way is home or what your elvows sitting on or what the guy next to you looks like while in convo, would it seem foggy or you wouldnt know/care?

All this not under the influence btw.
