brother and sister

This afternoon I got about 1 1/2 hours of peace and quiet while Ava napped and Thomas and Elle played outside. I hadn't heard any fights during this time and there was no tattling. When Ava woke up we went outside together to see what Thomas and Elle were up to and they were happily riding their bikes in the driveway. I asked them what they'd been playing and they said that they were playing brother and sister and that right now they were doing some BMX tricks on a ramp they built. Now if I could only get them to play as nicely when they are just being brother and sister in real life and not playing it. :)
