I've talked before about buying a measuring cup as a mug.
This measuring cup is really great.
For example, to make a cafe au lait, simply pour the instant coffee into a measuring cup, add 100cc of milk, 300cc of water, and toss it into the microwave.
"constant quality cafe au lait at all times."
So that's wonderful.

Wife: "I don't understand the sensitivity of thinking that's 'wonderful'"
Ebata: "I'm even thinking of buying one for the whole family..."
Wife: "Absolutely not"
Senior daughter: "Don't worry about that, buy me some fancy dishes"
Ebata: "Okay. I like the dishes too"
Whenever I go sightseeing, I buy local pottery for myself as a souvenir.

Ebata: "But I can't find anything with a scale on the inside of the pottery"
Wife: "Why is that...?"
Ebata: "Well, it will tell me at a glance 'how much stew I've thrown into your plate' and 'how fast I've currently eating the stew', won't it?"
Wife: "...
Senior daughter: "Daddy, that's what makes you 'happy'"
Ebata: "It makes me happy"
Senior daughter: "Well... If Daddy's 'happy', then I'm 'happy' too"
