I went to Internet cafe and looked for flight ticket home. I found one cheap option from Cancun to Brussele by JetAirFly in 48h. Cancun is located only 12h bus ride from Palenque. I thought a bit about this and not telling anyone about my plans I bought it and in the evening I was already in the night bus.
I did not plan to come back already but this was an impulse. I had a feeling that it is time for me to come back, so I did it.
