Boys are fish. Girls are squirrels. It's true.
Fish are easily caught. Put something sparkly in front of them and they'll bite without even thinking about it. They are just as easily distracted. If the certain something sparkly doesn't have a substantial hook (she's boring, lazy, high maintenance, involved elsewhere), the fish are just as easily un-hooked and they swim away never giving the sparkly thing another thought.
Squirrels. Now, they're more cautious. They see something of potential interest, like a nut, but they're not gonna rush right in a grab it. Nu-uh. They circle around it, finding out all they can about the nut before they're gonna commit to wanting it. And they'll try and keep the nut from realizing it's being evaluated. Once they've decided they want it, they rush in, grab it, and then hurry and hide it before some other squirrel comes along and creates competition. And the squirrel won't forget about the nut. She'll hang on to it for a good, long while.
There's a reason fish and squirrels don't co-exist. What on earth makes men and women think they can?
