Mo, on the hoity-toity discussion groups she hangs out in, observed someone talking about their tea balls, those things people use to hold their tea leaves when they are too Fancy to use a tea bag the way God intended.
She spent the rest of the day saying “tea balls” and laughing. This probably tells you all you need to know about Mo.
Other than that she then proceeded to draw the tea balls. And was then too embarrassed to post the results on her web site.
Fortunately we at Margarine have no similar sense of restraint. Tea balls. I like it.
