Willy and David

It was a surprise week-end in London for my son. It was the last day of Much ado about nothing. So we tried our luck. My sister in law was with us too.
There was a lot of people but those who were with us were very kind and nice. My boy managed a way to the barrier and said : "Bonjour David" several times. Then, David heard and here we go for the best dialogue of my son's life :

D - Oh, hello
W - ...
Sister in law - His name is Willy and he is french
D - Aw, really ? Would you like a picture ?
W (nodding frankly)
and then "clic clac" here is the picture.

This was, I think, the best day ever.
