Not the most diplomatic way perhaps... that said my patents told my sister and me that we were adopted when I was around 10. I'm none the worse for the experience. I was as pragmatic and philosophical (I was also nonchallant) then as I was later when given serious medical diagnoses. You have to try to make the best of any situation.
PS: that cake looks like a weird tank - are those supposed to be short gun barrels either side of the bumber? :?
