I talk to my girlfriend:
Are you leaving for a long time?
It is an hour
I - write to the ASU, I'm like this, I'll go in so much, I'll go back in so much (well, as if I'm joking, and that there's something to operate after her delay as a proof :) )
She is good.
A message comes:
“I’ll go out at 10 o’clock and come no later than 12 or 15.”
I am 2:15 is 1 hour?
She - Yes
135 minutes = 1 hour.
She - Yes

The shit! Now we know how they count the times!1! 1!
