First off Darv, I'm pretty sure a movie with that plot has been made a couple of times. I saw that idea in a porno or two...
Anyway Ning, we guys make it "light" because well, we don't really see the big deal. Here's the difference played out for you:
**Girl Scenario**
(Girl 1's dog just ran away, her baby's daddy ain't coming back, and she has a huge pimple)
Girl 2 (upon seeing Girl 1): Aww Girl 1, you don't seem too good. Is everything ok?
Girl 1: It's just a couple of stuff. It's nothing big really. (Girl 1 gives sad look to try to make Girl 2 follow up with more questions)
Girl 2: Are you sure? Let's talk about it.
Girl 1: Ok...if you really want to. So the other day, blah blah blah blah blah blah...
**Guy Scenario**
(Guy 1 has to pay the bills because he knocked up some chick but he's completely broke. On top of that, his dad recently just passed away and he lost his job.)
Guy 1: Yo man, whatchu up to?
Guy 2: Nothing. Why? What's up?
Guy 1: I'm just bored. Imma come over to chill all right?
Guy 2: Cool.
Guy 2 (upon seeing Guy 1 and noticing something is probably wrong): Yo man, what's up?
Guy 1: Not much. Just one of dem days...
Guy 2: Cool. Wanna play some Madden on the PS3? It has some sick graphics man.
Guy 1: Yeah sure. That sounds awesome!
Bam! That's the difference between guys and girls. NOTICE also that girls try to use that ridiculous look at guys too when they want guys to ask more questions. Most guys do notice when things are wrong. HOWEVER, if a guy asked once and you said "nothing's wrong", he's not going to want to play the guessing game anymore. Girls will continue. Guys will stop...at least, I know I will.
Anyway, this isn't meant to take anything from Tina's thread. I'm just explaining why guys will probably joke more when it's about something like this.
So...imma go play some Madden now. It's sick.
