I find such sentences puzzling. How can you not know? At 17, being obtuse may be your a birthright. At 25, not being able to tell who wants to get into your pants is plain stupid.
My boyfriend ( I think I've begun to refer to him as Junny) is a classic example. He just can't recognise a fawning woman. You can be wearing a low cut black number and murmuring, "Really, you play the piano? Can you teach me sometime?" and he will overlook your tone, cleavage, intent and just be so happy at interest shown that his "sure, anytime" will be genuinely short sighted.
Me: She's coming on to you.
He: No, she's not, poor thing, leave her alone.
Me: Trust me. I know these things.
He: Is this the only way your mind works?
Me: Ugh. Fine.
He : Ugh fine yourself.
Really, men can sometimes be more obtuse than 17-year old girls.

The thing is, I love flirting. It's fun, it's distracting, it makes me laugh and if well-done, makes me imagine a scenario or two and even run my fingers through my hair in slow motion (but not too slow). 'Carefully careless' is the term a friend used to use. But then he fell in love with me and became a killjoy. But that's another story.
The great part is that flirting gives ugly men a chance. You can be fat and have bad teeth, but if you have the confidence to be goofy, honest and flirt well, we're all ears.
- Make me laugh.
- Don't say LOL, (always Ha Ha).
- Don't pretend you know about the government when you're more like Chautala who.
- Don't quote song lyrics in texts (unless you've written them).
- Don't use too many smileys.
- Don't hesitate to compliment.
- Don't lie.
- Don't hold back.
- Don't fear getting spurned.
I'm not sure it works well the other way too. Do men care about women being good flirts? Do men care about men being good flirts? I could be wrong, but the straight ones all just want glossy mouths and big breasts. Really.
