If you were at a party with your best friend...

This party consists of you, your best friend and 3 other boys. Your best friend suddenly leaves the party and says nothing to you. Would this be remarkable in your mind? Would you not be asking your best friend later that night or the next day what happened, where did you go, why didn't you let me know you were leaving, etc. Once you learned that someone attempted to rape your best friend, would you not be curious as to why you were left to be the next victim? If this party had occurred, her best friend would have remembered! She remembers no such party. Case closed!
