English Strikes Again

Today we were at an assembly at our kids' school. The principal was talking about a USB key and Chris leaned over and we had the following whispered conversation:

 Chris: "What is a B key?"

Me: "A USB key."

C: "I don't get it. What's a B key?"

 Me: "A U-S-B key. You know, for a computer!"

 C: "Like a flash drive?"

Me: "Exactly."

C: "I can't believe I just wasted 20 seconds of my life. I thought he meant a B key from the US. I hate English!"

And what followed was that awkward moment when you are dying to laugh, but totally in the wrong place to laugh out loud. So, you hold it in and try to laugh silently. Except the laughter turns to tears and escapes through your eyes. And you are sitting in a assembly where the principal is talking about USB keys and nothing, not one thing is funny.
