I seem to miss even the biggest signals of attraction. For example this girl wanted me to pick her up and drop her off at her house .she kept mentioning how she was all home alone and she had nothing to do. Before I dropped her off she stared at me and smiled but then drove off and im only realizing what it meant now. Ive also had girls kino me(touching my arm slowly, playful punching) and I just brush these things off and don't respond. How can I avoid missing these clear hints? How should I respond if i pick up these hints?
