I am happy.
I am happpy for a friend.
I am happy for a friend who is happy.

From what I have heard, the signs are promising and so I am happy.
You know something, it was a good thing that we did not go to the airport last night. By not going to the airport, we have confirmed certain things, and the things are good. Maybe you already know that, but to me, it is something a little new. For that, I am happy.

Seems like a happy day today.
What about you? How do you feel today?
