We all need Backup

In the movie "About a Boy" with Nicholas Hoult and Hugh Grant: almost funny, almost sad, sometimes hopeful, other times hopeless, but truthful when saying:

All I meant was I don't think couples are the future.
You need more than that. You need backup.
The way I saw it, Will and I both had backup now.
It's like that thing he told me Jon Bon Jovi said:
"No man is an island."
