I took a girl out on a date on friday, went to grab an early dinner and then went shopping (for me) anyways I noticed on facebook, that she and her roommates had a keg party on saturday, i find it strange that she didn't tell me about it, seeing as I asked what she was doing this weekend and she failed to mention about hosting a keg party. Am I over analyzing the situation or is this a sign that shes just not interested?
