I am definitely NO Czech expert, but my small vocab would suggest:
Jsem na ulici, pred budovou. I am on the street in front of the building.
Pron: Semm nar oolitsee przed boo-doh-vo-oo (again try to run the r and z together)
Jsem ted' tady. I am here now.
Pron: Sem ted tuddy.
Luck has nothing to do with it.

Uz rozumim slecno!
Of course the afternoons were free to do my 'Homework'
