not even a word back, as an answer: how rude...

Ok, this is the story: you write to a girl, already friend of yours, in your friendlist. you are not pervert, not vulgar, nothing like this. You make simply a gentle joke, or you say sth funny but in a friendly way. No answer. You insist, opening yourself, being polite actually. Zero. You sent another mail, asking politely if girl is interested in talking to you, contacting with you finally or not. Nothing: not even one word! She reads the mail, you see it, but.. not even one word as answer! Sth like "no thanks, i have no time for this", or "i'll do when i want, don't push me".. Something! But no: not-even-one-simpe-bloody-word... And then most of women keep talking about.. perverts and rude guys..! Who is really rude??? I wonder... But at least my grandma used to tell me that this behavior above shows total lack of good manners...
