Gelato in Venice

So I'm chatting with a friend recently and we're reminising over a trip to Venice some twelve years ago. I recall sitting on the Piazza San Marco late at night; we'd been to a Vivaldi concert earlier, were probably eating gelato (we ate a lot of gelato that trip).  Just kicking back and watching the world slowly pass by. I took this photo as we sat there. 

My friend says yes, he remembers sitting in the square - a couple dancing, and then another couple having a loud argument. I think the guy threw her suitcase into the canal, I add.

But the more I think about the scene I'm not quite sure. In one version she throws his suitcase into the canal and in another he's doing the throwing. But there's another version again where he tells her that he threw her suitcase into the canal, but actually didn't do it. There was definitely a lot of shouting but the more I try to recall the actual events the more my memory fails me.

My friend can't help - he can still hear me laughing but doesn't recall the suitcase aspect. But he kindly says it's a great dramatic touch and offers to add it to his memory.

So I'm wondering, does my poor memory make a dishonest woman of me?
