Quartet of fun

Boys joined our upstairs neighbours for a day of fun. They set up a sale stall and even though a great deal of effort was put into drawing attention to themselves, they sold ... em .... nothing. But had great fun doing it. (They have decided to postpone to a better day - like a Sunday afternoon!).
After lunch two local parks were visited, rocks climbed, big swings, and M found that too much time on a roundabout will result in him feeling sick.
