You know if he fancies you when....

This is on yahoo
A man fancies you when he....doesn't talk to you (he is shy), teases you, hides from you, doesn't remember you, suggests splitting the bill on the first date, if he flirts with your friend or babbles nonsense at you....

WTF. A man doesn't remember me, wants to split the bill and hides from me? And I just thought the cowering in the coal shed when I came round was him saying no thank you....

4. They don’t seem to remember you

So, you had a brief drunken encounter six years ago, and it has faded from their memory. That’s what they want you to think. They want you to think that they’re far too busy and popular to recall it. In fact, the memory is etched onto their brain and lived out in filthy fantasies every single night

ffs - there's me thinking I'm resigned to the shelf, but turns out nearly all the guys I know really fancy me

...when he would rather spend the evening with you than with his muckers down the pub

This sums it up.

With Crows,  they flap their wings really fast and

they walk round and round the hen  pecking her neck until she notices him

Pidgeons do the same as well
