just out of curiousity

well since i love asking questions to see the reason why people do the things they do, i have one that i haven't received a reasonable answer to.....and here it is:

WHY IS IT THAT GIRLS FREELY DO STUFF TO GUYS WHEN THEY KNOW IF IT'S DONE TO THEM THEY'LL GET EXTREMELY MAD, CRAZY, SUICIDAL OR WHAT NOT? *RAISED EYEBROWS*......
 for example a girl can keep a guy waiting buh if a guy keeps a chick waiting.....all hell could break loose........i actually believe most girls are impatient tho...(my opinion)...
