How often do you clean the car?

Not often enough. Every few months. Often think “Shit, I need to clean this fucker”, but rarely do it.

I’m afraid “gaggle” is not an accepted collective term for swans. You could go with lamentation instead?

Fair clarification. Enjoying the fact that you overlooked the notion of swans living in trees lining residential streets to make it.

My favourite will always be a Parliament of Owls in terms of bird groups. Elegant.

Once a month inside and out in Summer, Once every 2-3 months in winter, with the occasional quick interior clean in between.

I have cleaned mine once since I got it in 2014
I hoovered a bit inside but didn’t do a very thorough job
