What things can a 16 year old do for entertainment with their 11 year old sister?

I am the oldest of my siblings, so finding ways to keep them entertained was something I did a lot when we were younger.

Things to try out:

• Play video games together.
• Go out and play soccer or just kick a ball around. When there were only two of us, we'd play a game where we take turns shooting the ball against an area of a wall - and the next person had to kick the ball on the rebound.
• Create a magazine. We'd each write articles for the magazine and draw in pictures. With all the technology at your fingertips these days, that could be much easier these days.
• Watch a movie that you'll both enjoy.
• Make a board game. That could be fun!
