*laughs* We have at least very different sizes of "ordinary" mugs, quite apart from the ginormomugs. As for rice, we have a little metal pot that has lived in the rice tin for many a year, which gives enough for the two of us... but... (suddenly pauses) it's a lot smaller than a mug. *goes down to check.* Okay. The amount of dried rice we cook for 2 people fills a third of a mug. Clearly we have either very big mugs, or very small appetites! :-D
