1. Smoking (I've been there, before, but even when I did, I couldn't stand the smell! It sticks to cars, furniture, clothing... Ya can't get rid of it, and there's nothing sexy about it!).
2. A lack of awareness to one's surroundings (Sounds obscure, but seriously, these are the people who stand in your way when you're trying to get someplace quickly. These are also the people who will cross the street obliviously, while the "Do not walk" sign is lit, and a big truck is barreling towards them.).
3. Non-prescribed drug usage (I'm not attracted to people who put themselves at odds with the law. If it were legal, recreational use that wasn't abusive might be a different story--that is, unless it ties into number 1. 😉 ).
4. Financial irresponsibility. Financial train-wrecks are a HUGE turn-off. I've noticed that desperation in this department tends to make one manipulative, which leads to...
5. Manipulative nature. There's absolutely NOTHING attractive about that.
6. Bad hygiene. I understand that many women go through a LOT of work in the morning to maintain their appearance, but if you're not showering just because you'd then have to redo/straighten/blow dry your hair, or something else, and you just don't wanna make the time for it, I'm sorry, but that's nasty. At least shower!
