Answers needed!

Oliver, my 4 year old grandson, wants to know the answer to how and why with everything.

Answers please - Why can't Great Grandpa and Great Grandma jump down from heaven to come and see us - and how did they get there in the first place ? Not sure how to answer this without giving him nightmares!

Sometimes it is just easier to answer his questions in a practical manner, so here he is having his first lessons in Grandpa's workshop. He took home a piece of wood with lots of holes in it to show his dad - he was very proud of it.
