Assumptions

The root cause of all troubles is assumptions

Driving late in the night..there is a crossing..just turn (the assumption is that no one else will be driving so late) and there comes someone who thinks the same...and then  bang.#@$&.

Had a small misunderstanding with a childhood friend, "No..I am not saying sorry, she/he is the one who should be saying sorry..Ok even if its my mistake..he should be the one who should say sorry if he values our friendship"(again assumptions)

Year end test....Let me me go through the last 3 years papers..surely majority of the questions will be repeated_____Exam time..Oh oh what c**p..How can there do this..it always happens to me"
(Again assumptions)

New Movie released...Oh this has my fav actor in it..he can never let me down..he is always given good hits..Let me call her..I will surely be a good time and will be easier asking her out for the prom .."Hey! It's me. Lets go for the movie.its my fav actor..it will be fun...ya i will pick u up at 6.00"..and then___oh oh how can he sign up fo a movie like this..it ought to be a good movie
(Yes you guessed it right ..why it happens)

New gadget...I gotta buy this..let me search on the net..for its reviews..forget it..its from XYZ..it gotta be a hit___So take out the savings ..buy...and then __the scroll does not work..its a phone, how can the sound be so pathetic..it's from XYZ..its in the busines for so long..how can it?

Good time last forever? Friends are always gonna be there , Sweetheart is always there, Family is always there..the current job is always there...IS IT?

So whats the Root Cause?
