Another little gem

They just keep coming, bless his little cotton socks. On waking this morning I was met with one of those big questions that occupy the mind of a 7 year old. Well my 7 year old anyway (aka the "Pod" - see earlier blog!) The conversation went like this:

Pod: Mum, are there any Mediums up in space?
Me: What do you mean?
Pod: Rocks that hit planets.
Me: Oh, you mean Meteors - yes there are!
Pod: If they hit the Earth we'll be ok....... there's a big field.
Me: Oh, that's alright then!
