I’m more than his Alien!

He suggested that we watch Martian and that I’d like it. I agreed, rather reluctantly. Whilst watching the movie, I asked him if he’d ever like to go to Mars. He said yes, to which I asked him ‘then why don’t you?. He said he’d need immense amount of training and knowledge to be able to go there, to which I asked him ‘why don’t you?’. He took his eyes off the screen, looked at me and said ‘I’m actually happy on earth’. I smiled and said ‘because you’ve got your alien here! ‘You’re more than an alien’
