why am i so unintentionally cold

just the other day i was reading a book on my kindle and this guy i think is really nice asked me “hey what are you reading” and i just shrugged and didn’t even bother to make eye contact and said extremely awkwardly “it’s just something you probably don’t know” and once again lost the opportunity to have a conversation with someone i’d like to have a conversation with. i don’t do this intentionally and i hate that this happens because i come off very cold and uninterested in those around me when inside i actually love people and really want to make new friends

does anybody have any advice 😭😭
