I have no interest on what your last meal was. I don't want to see it on Instagram, and I sure as hell don't want to smell it whilst you're invading my space and talking to me close enough to kiss.
If you're not telling me a secret out of necessity, or kissing me - there is no reason for me to be able to smell or taste exactly what your last beverage was. I'm going to go ahead and say that if you're any closer than a foot from my face you're talking too close to me. I can hear you. I just don't understand why some people feel like they need to be that close to talk. Are my eyes THAT pretty? Are you trying that hard to read my facial expressions? Or is it that you want to smell my last meal? Because that's impossible - I'm holding my breath so I don't have to smell yours, soooo we're at a stalemate here.
If you're within your 1 foot radius and you're a man - you're within head butting distance and I'm listing you as a threat. If you're within this radius and you're a woman - you're within kissing distance and now I'm uncomfortable and probably unwilling to continue the conversation... Or executing kissing phase.
