Going to Stockholm for my birthday

Im going to Stockholm for my birthday (on Sunday), leaving tomorrow, wont be back untill Monday. Probably I don´t have a chance to write hear before Tuesday. On notes on my trip, its amazing that my trip to Stockholm cost less than it cost to go from her to Gothenborg, almost, with travelling when you are in Gothenburg it is cheaper to goto Stockholm (but for sure, the travell in Stockholm is more expensive).
