I Missed my Bus!

I lived in the Mexico city and decided get back my home for the weekend. In my opinion  Mexico city is dangerous and  big. So I called at bus station, I asked when the next bus for Puebla.

After I taked my suitcase and went to bus station, But I only missed  way in the bus station by a few minutes.

I was scared and annoyed, because I didn´t remember how to get from San Lazaro to the bus station "TAPO".
So I walked a little in the station San Lazaro and more later I searched the correct output a the bus station.
Hrs later I remembered in my house that I missed in the bus station.
It was very frustrating.
