What everyday objects become surprisingly challenging to use in zero gravity?

I’m sure there are plenty of other things.

Things like drinking cups really don’t work - neither do hard glass bottles. You have to force the liquid out by squeezing the container and drinking the liquid through a straw..

Toilets are notoriously difficult - if I recall correctly, there is something like a three day training course for astronauts to learn to use the ISS toilet before they fly there.

My wife has a bunch of really attractive friends, and she expects me to never say anything to her about how beautiful they are. Does this seem fair? I love my wife, and just commenting shouldn’t hurt anything, right?

For some other things - the astronauts have to use a seat-buckle - for example, typing on a regular keyboard gradually pushes you backwards until the keyboard is out of reach.
