Super Friendly Addison

Today we went to the park, because it was such a beautiful day. At first Addison was playing her heart out. She was running around and going down the slide and I pushed her in the swing for a long time. But then other children started showing up. After that, all she wanted to do was follow the other children around, continually saying "Hi." She said hi at least a hundred times. At first the other children (who were a little older) would say hi back, but after a while they just started to ignore her. I want her to be friendly, but I don't want her to be annoying.
