Its just one aspect of their lives. For all he knows they could be struggling with debt. They could be "just servers" too for all he knows. Like at Cisco, I hear they have a lot of servers. Good opportunities all around!
There's no reason to feel envy towards a couple that "found each other" already in their teens. Be single, date, hook up, make mistakes, try to learn from them, get high, get depressed, get drunk, get up, grow as a human, etc. while you're young. Eventually you'll find someone that'll have gone through the similar ordeals in their lives, and the chances are good you'll live happily ever after.
This just sounds kind of egotistical to me, why even compare yourselves to them? Be happy for them, get over yourself.
EDIT
The downvotes tell me that you all need to get over yourselves. Stop obsessing over other people, live your own life. Someone elses accomplishments do not diminish your own, and different people meet different milestones at different times in their life.
Y'all need to get off the computer and go live life.
It's possible to feel two things at once you know.
Anon can both be happy to see this couple go through their milestones, and also feel a bit sad in feeling that their life has stalled by comparison.
Is it a good idea to live your life comparing yourself to other people? No it isn't, but even if you normally don't, there are times that feeling can creep in uninvited anyway.
