You know, Fred and George are really clever and they can do loads of advanced stuff, but they actually can't do everything. We can't always count on them being able to just whip stuff up that no one else can.

Actually. You should have seen this summer, there was this time they were helping with supper, and they were using sending charms to get everything on the table, only they flung the knives across the room so fast, they nearly killed us! Me and Ginny, I mean. Luckily we've got good reflexes.

So, I don't know. Maybe they could learn it, but I don't think we should plan our whole escape strategy around them doing that.

I'll ask them, though.
