[Jeff Robertson]

well i knew this girl from my english class and we sit right next to her, but weve only talked maybe 2 times and on friday she and i started talking on twitter so I chatted it up and I sent her a gmorning message the next day- she favorited it and retweeted it. I kept commenting on her stuff and she favorited alot and as soon as I say hey i gatta go, can u text me- she didnt respond... I was worried. but then i commented again and she favorited that. then I said good night- no comment. then I said gmorning and she favorited that this morning... whats going on here? does she like me? is she playing hard to get? what does this normally mean from a girl
