Might have missed my chance 😔

I was talking to the sweetest guy on tinder while I'm in the city visiting my sister for a few days but he's leaving tomorrow for over 2 weeks and we both really really wanted to meet up and he was saying such sweet things but I'm staying with my sister and she doesn't believe in meeting up with strangers, which I understand it's just still frustrating. I am 20 years old so I could have just left without saying anything but I respect her and the fact I am a guest in her home too much to just go behind her back. She obviously was very against it and I don't like upsetting her so I couldn't meet up with this guy and I'm so bummed out because we live far from one another and it would have been so nice to have had some attention tonight. Oh well. If it's meant to be, it will be I suppose 😔
