I know how to...

In class the other day I was teaching the kids that "I know how to..." means the same thing as "I can..." As an example, I said "I know how to play baseball." When I asked for volunteers to try to make a sentence, of course they all said "I know how to play..." So I asked them to make a sentence without using the work play. Imagine my surprise when one of the boys in the back raised his hand and said "I know how to love someone." I had to try really hard to restrain my laughter. This is also the class in which one boy, when asked to make a sentence using "I like...", said "I like American girls."
