It's healthy to have older friends. You go 'Look I'm younger than them!' That's always the nice thing if you can be the youngest one in the room at times. Like if you're always the oldest one in the room you'll start to feel like the oldest person in the world. So get older friends because they're cool. Get cool older friends.
That's a big deal for kids when they come into the kitchen and the teacher is drinking coffee with mom. They react differently on the next day when you say: 'Sit down and shut-up!'
