Bad luck

I was supposed to start the next day very early in the morning or better said - in the night at 2 o'clock. In the evening i was going to gas station and i 'felt' that something wrong was with my car. I got off, had look at the wheels, but everything seemed to be ok.
When i was back home - like 22.00 i had another feeling, like 'must' to check the tires again... and i was right - one of them was without any air:/// (#$#%$%@@$#@$@$%@!!!!!!!). I've tryed to change the wheel (lucky me i saw it earlier and not at the time when i wanted to go to the airport). Unfortunately it was getting dark so i was changing the wheel almost in the darkness - but... i did it! and i did it fast (like 5min) haha!

Then i was trying to sleep at least 1-2 hours...
