I asked a girl out from work as she always gave me great come-on smiles every time I would see her. I did it by SMS as I was a bit shy. After three days and hearing nothing I sent her another SMS and she replied saying it was her birthday and she would have to spend the time with her family, so sorry. What do you think, Hillary? Was she letting me down gently or should I try another SMS?
You are certainly a bit thick. If she wanted to go out with you she would have suggested a different day. You have mistaken a Thai smile shown to you for interest in you. Keep looking, but that one write down as experience.
