Since people are naturally social, the people around them are inevitably going to affect their state of mind - especially if we have a desire to be around them.
People, I'm happy that they are there, but no they don't make me happy.
If I can't give meaning to my own life, who can give it to me?
E.g., parents rate relatively low on happiness yet are still "happy" that they have children. They have a sense of wellbeing from something meaningful.

In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.
- Wordsworth
