Don't do this. I catch men doing this a lot, when at a party they have no courage to approach a girl, so they just stand close to her looking like a sad dog instead. I'm pretty sure this is a clear message to the girl: "I suck and have no self steem, pity me".

I guess this is the same look you give your oneitis, even though you pretend you don't like her. She'll know. How do I know? Was sleeping with her, it was morning already, she was mad at me but still I wouldn't get the fuck out (even though there was a voice in my head screaming for me to fucking leave), oneitis then told me: "stop staring at me like that".
