I just can't understand... Is it really THAT hard to lose?!?!

I play this game just and ONLY for fun... What else can I get from it?! Money?

A candy? lol
Sometimes I start playing and my opponent just enters the CHAT and writes "I gotta go". That is totally enough and understandable! Sometimes I must go somewhere during the game, and I always inform the other player...
I just had several match when I reached match point, and my opponents entered MENU and stayed there, refusing to return to play until the end, and to lose, or maybe even to win (who knows)... It would be even understandable if they just quit... But no, they just don't let you play to the end. They just want you to wait and wait and wait... and wait... Until you quit. It looks like some ppl here don't have a REAL life besides Tennis Elbow, so they have to do this tricks to be satisfied with their life
My
ELO is about 1350 and I'm a PRO now. But I often lose to CLUBs and JUNIORs, but it just doesn't matter... In every match you learn something more. Yesterday I lost twice to JUNIOR players with 0:6... So what?! Had great 7 minutes while playing...
That is the gold of the game... You can't win them all...
Without this kind of players this game would be perfect.
