Day 7 (Patience)

For those people that know me and say I lack patience, today I started fitting the shingles to the cabin which entails the following :-
11 bundles to a cabin.
110 shingles to a bundle.
Each shingle has to be cut in half.
Each half shingle is nailed on with 2 nails.
......and if that wasn't enough I have to contend with these 2 monsters knicking my pencil, climbing all over the piles of wood and wanting to play football all day long, guess what's got their attention in this pic ?
