My grandson asked why I always put the colander in the cabinet but rinse his blueberries in a coffee mug

I told him it's all about strategic vessel selection.

The colander lives in the cabinet, yes. Clean, organized, ready for its close-up. But when you're rinsing six blueberries at 7:08 a.m. and the bus comes at 7:12, you grab what's already in the sink.

Punchline

The colander is aspirational. The coffee mug is operational.
