Having a philosophical discussion with my SO, who thinks it’s unreasonable that I use four different mugs in a day. I work from home so I’m here all day and I do drink a lot of hot drinks, so how many is too many? I have an instant coffee cup, a filter coffee cup, a tea cup and a mocha cup. I don’t expect anyone else to wash my cups and I like different sizes for different things, so it doesn’t seem unreasonable to me…am I wrong?
