0. I didn't have to, I wanted to.
1. Because I can.
2. To make him smile.
3. So we can all see it the right way round.
4. To have an excuse to show it again because I like the bold audaciousness of it.
5. So you could comment and enjoy it again.
6. To give me an excuse to properly compliment him on his outfit.
and most of all, I enjoyed doing it.
