Translation of schwatzhaft

I hope you could understand my last letter to you. You see, when I write in Spanish I am not very confident. I always question myself and each and every sentence takes about fifteen minutes.
How could I get better in Spanish if I had to eat by myself. Impossible. The next days we always ate together and sat around the table for hours discussing politics and the lives we were living.
Usually I do not care too much about not getting change, but when you pay a 3 dollar ride with 50 dollars, you do actually expect change. We stood there for a while and neither of us knew what to do.
