This morning, as we were eating breakfast, Amy looked at the carton of milk on the table and said, "There's an aitch on it!"
And indeed, there was: a big H in the background, taking up about half of one side, presumably because it was UHT milk (known colloquially as "H-Milch" in Germany).
So we started looking for some more letters. "Do you see an eff?" "What's that next to the em?" etc.
Then I told her that the letter next to the M in "Milch" (written in a sans-serif font) was a "small eye. Look—it's got a dot on top. Do you see the dot? Small i's have dots on them."
And Amy said, "And next to it is a big eye!"
Nice try—unfortunately, not this time. "No, that's a small ell. But you're right: a big eye looks like that, too. Small ells and big eyes often look the same."
