I was thinking that the baloons and ribbons on the walls would come off by the time the party was over. But I was wrong, no kid asked for a baloon or pulled the ribbons and all of it was still on. After being kept there for some days, the ballons deflate or burst or come off the wall but we usually we don't take off the decoration after a party. May sound stupid but I like to leave it on as the reminder of nice time we had.
