There was a campaign going on a year or two ago called "More Alike Than Different". It highlighted the ways that people with down syndrome are like everyone else - actually, they are much more like everyone else than they are different!
We especially see this when watching Ace and Munchkin. They have very similar personalities, are both very bright and eager to learn and are both very creative in how they do it. They have a lot of fun together, as seen in this picture below. This was all them - Ace lifted Munchkin into the basket and then got one for himself. Just two siblings hanging out together, watching television.
