Exactly what I feel and think about. If I don't welcome myself into someone's life by conversing, how can I know that they can be my friend? It's really weird, honestly. As a kid I can understand this.
Maybe you just instincively saw epicness in the new friend. Or he/she is a friend of another friend who you knew since childhood. Or you have a strong genetic link you don't know about. Or maybe I'm just thinking way too deeply into this...so i'll stop here.
