Fancy meeting you two here!

Was wandering around the M and S in Bluewater to try to find some casual clothes for HG. As his idea of clothes shopping is well documented and he is in desperate need of some casual clothes ie shirts where you don't need to wear a tie I tried to make things as easy as possible and bought them myself.
But who should I see in the men's department but son No 2 and Piers.
" Mum, what size waist and inside leg do I need?" He asked!
It clearly runs in the genes!
