Well, duh

 It wounds me that you might imagine I could make such an obvious mistake.

Who?

"Do you remember the time we had to pretend we were having a party in your house so you could get that fella you fancied up to your house after the pub, so we grabbed Olga and said "Come on, Party!" and we brought him and you were mad at me because twenty minutes after getting home I said I was going to the loo and just went to bed and you were left pretending this was a preplanned party all on your own. Did you ever kiss that guy? He was tanned and was just back from travelling? He fell asleep on your couch and you and Olga drank vodka? Who was that guy?"

No. Literally, nothing. I remember none of this memory of Marie's from approximately six - seven years ago; not the guy, not the night, not the party. I do recall randomly hooking people under my arm to bring them to impromptu parties (I still do this!) and I definitely recall Marie sloping off to go to "the bathroom" at parties and being found curled up in a bed asleep half an hour later.  This maneuver is called "doing a Marie on it" for this very reason.

Expenditure

Just cleared out my small glittery wedding purse from last week's wedding.

 Looks like a busy five minutes for me and Niall there.
