So i met this girl on facebook and we been talking more than a month. She always from begiming wasn't best texter and she usually replay slow or there are moments when she replay more. So ii was telling her 3 weeks i am coming to visit and last day before i reminded her i am coming. She said i am sorry there came up new project that she will need to do on day we haf to meet and probably we won't meet. So i though dam i am coming for her and she doesn't even have time to meet. Than when i arrived she messaged me on her own and asked if i arrived and if want to get breakfast and she picked new places. She told me she never been to this places so i said alright. They were around 10 or to 20euro per person. Not cheap but not the most expensive. When she came she ordered deal for the day. And i think she still wanted to try pancakes which she shared with me. I paid for it all. She was a bit tired after day before she went to party with friends and she spilled something on here , plus it was bad westher coming. We went together near here home and said good bye as we spoke she will sleep for few hours and we meet again. Than i went to the city expecting later she comes again i waited anf waited she than texted me once an hour and said sorry she forgot to mwntioned that she is taking photos for that project. But than later she posted video she is with her friends in tv tower and i felt like idiot waiting for her... and she went not with me but with her friends.
