What happened?

What happened to my sons?
They've changed somehow,
They won't discuss things with me anymore, And they arrive home late all the time now.

Jake often looks like an old man,
And Tom sometimes looks like he is caged.
When I see them play, there hearts are not into it,
And both of them looked like they have aged.

I sometimes wonder if my sons are part of a gang.
I also wonder what changed my two sons?
Why won't they tell me?
What should I do? What are my options?

They clam up in the face of my concern,
Perhaps I've made a parenting mistake,
Tey avoid my questions, retreat to their rooms,
What's wrong with Tom? What's wrong with Jake?

What happened to them?
Why won't they tell me what's wrong?
What did I do?
I don't know, but I really hope that their life is happy and long.

If you have a spare moment please review! I really enjoy reading them. I also really want to thank the WretchedOne for helping me make the fourth stanza even better! Thank-you WretchedOne.
