Leaving Porto heading to Madrid........

So after saying my goodbyes to Rafael and his family.Clara's father gives me a ride to the train station,i board my train and i'm on my way.Aboard the train i sent and think about the last couple months,where i've been,all the long bus rides,train rides,and wondering whats next.As the time flies by we finally reach the last stop and it's 1105pm with 30 minutes till my next connection.I get off and realized im in Lisbon!.Now according to the ticket guy he told me what time i would arrive and that i would have a 15-20 minutes till my next train to Madrid.So of course i did not look at the train stops and now i'm stuck in Lisbon for one night!NOT COOL!NOT COOL AT ALL!Now i have to find a hotel for the night and buy a new ticket.70 euros wasted!So i get some directions where to go in town to find a hotel which meant a 30 minute subway ride,then the hotels i find are all high end places and its after midnight,so i check in the first place right upstairs from the station.77 euros for the room.The next mornig i get back to the station and they tell me there isn't an available train till 1030 at night and on top of that i can't get a refund on my ticket unless i send the ticket back to my buddy's place in Porto where he can get the refund of 30 euros but it would take atleast a month to get it back!Now i'm more pissed!But he tells me to goto the bus station and see if theres a bus to Madrid.I get there and there's one bus available for 40 euros and it's 8 hours!No choice but i do it and im off.Almost 200 euros within 24hours spent all because i didn't check the stops.Number one rule when riding the train abroad:READ THE STOPS !IF YOU DON'T KNOW ASK A PASSENGER!
