I fell in love again! Long story short; I saw a generous girl today getting on the train. Her cute smile made my heart skipped a beat. Just before she got off the train, she gave me a "I acknowledge your presence" wink and "Im single" smile (well, thats how i interpreted it). And my friend who was present at the time said he knew the girl from his highschool, and he gave me her number.Sooo, what should I do?
