One of the biggest differences between Teen and Adult chemo, is visitors. Though Adults often have a spouse or grown child along to keep them company, children and teens often come with a larger entourage - both parents, sometimes siblings or friends, and they often have other visitors who drop by for an hour or so to hang out.
The TYA is set up for this, and is very welcoming. Each patient space has lots of room around it for companions to sit, and there are stacks of chairs at both ends of the centre, so there's always a seat for everyone. It's actually very comforting to see that the kids have such solid support networks; I suppose that's why the nurses never seemed to mind. I enjoyed drawing these groups when they appeared; the interactions were always enjoyable to capture on paper.
