mistery questions

These random questions suddenly pop in my mind while i stares the ceiling,trying to get an afternoon sleep :

1. My room is upstairs.I have to use the stairs every now and then,whether to go the bathroom,kitchen,or going outside. Imagine i take the stairs 10 times per day,that means 70 times per week,280 times per month,3360 times per year.
How can I make sure that not even once i will fall down from the stairs?
creepy

2.A couple of days ago,i had a little chat with a friend from elementary school.I know we were at the same school,but i barely remember whether i was in same class with her.
But she-surprisingly-remember me very well. She told me we were in the same class at 2nd grade,and how she called me 'Anin' not 'Dita' like any other friends. I felt flattered she remembers me,but even more stunned after she state the reason why she remembers me
she said : i remember you,because you were good at drawing
her simple statement made me realize how much i used to love drawing.
As far as I remember,I was always drawing all the time,I couldn't resist the appeal of a blank paper
In fact I made several short comic
I drew and drew all through my childhood and teens.
until i got accepted in FSRD ITB,which i really want to get in
but my father didn't let me
so we had a fight and i cried for days
and i stop drawing since that day
i never ever made a single real drawing since my university life begins
i haven't draw anything for 2 years now
and now I realizes that,i felt like crying
Why do I stop doing something I used to love so much?

I'm gonna go buy a sketch book later

3.This morning,after Computer Programming tutorial class,i bumped into a girl on my way home.
And she was talking to herself
And no,people,she was not using any handsfree,nor ipod and mp3 player
she was talking,and her expression was somehow a little angry
she passed me,still talking,left me speechless
Was that for real ?

4.Okay seriously,are we having Database System tutorial class this afternoon ?
I really want to sleep but feel rather disturbed because some people said we are having it,while some other people said we are not.

Well,let my mysteries remain seated
What's yours?
:)

P.S : Oh,and that girl from my elementary school,she goes to FSRD ITB now
yeah right,life can be so ironic sometimes
