bourdon

Je me souviens qu’un jour, étant enfant, j’allai voir le bourdon de Notre-Dame.

I remember that one day, when I was a child, I went to see Notre-Dame's great bell.

Je me souviens qu’il écrivait ça à un de ses copains qui avait le bourdon et qui voulait voyager. L’autre lui disait grosso modo que c’était pas la peine étant donné qu’il allait se trimballer son paquet d’emmerdements avec lui.

I remember he wrote that to one of his friends who was down in the dumps and wanted to go travelling. He basically told him that there was no point since he'd just be taking all his problems with him.
