Did I Not Just See You Upstairs?
It could get rather confusing at a party if you had a conversation with someone in one location, then you find yourself in another location getting introduced to them, again? All this – only to realize that there are two of them floating around at the party?
Two options – these two are either twins or do not even know each other. We vote for the second answer, and it must have been fun introducing them to each other in the end. Could you imagine having learned you have a double in an instance like this? This would at least make for an interesting introduction.
