Why do flies shit on our HomePod?

It's a little hard to see in this picture, but there are several black flies sitting on our black Apple HomePod, which has dots of black fly shit on top. Why do they do it? There's nothing in the user guide.

Oddly enough I haven't seen this commented on. It's rare to get a dead end on Google.

Things you can't do in Madeira

Gender neutral icons

Classic Isotype charts are sometimes referred to as 'rows of little men'. But how could we instead show rows of little persons?

I love this gender neutral icon which Tesco are using in their supermarkets. Just by stretching the arms out a little, it allows people of any gender identity to see themselves in it - it could be wearing a dress (or have wider hips) or perhaps its arms are just positioned like this.

The Noun Project has various other attempts:

The one on the left by Dan Brunsdon is typical of solutions which just combine icons - not so much gender neutral as both-genders. 

 I quite like the right hand one by James Walker, with its suggestion of hips.
