. . . we have ants.
I think the wimpiest ants in the world live here. Unless it is warm and sunny they come inside. If it is raining, they want to be dry. If it is cold, they want to be warm. Not that you can really blame them, I guess, but I though wild animals are supposed to tolerate weather.
And these little creatures only show up in the bathroom. I’m not complaining, just mentioning that they almost never invade the kitchen. What is it about Bon Ami they find so alluring? They race endlessly around the edge of the wash bowl, going nowhere in a big hurry. From time to time one of them will climb the alps of Mt. Faucet, but for the most part, they stay on the counter.

I will chalk the edges of my kitchen sink to prevent them from every coming. I hate ants and in tropical hot and humid Singapore, plenty of them. If ever you spill or drop crumbs, ants will be sure to arrive.
