What should I do...

Is it better to ask her about it?

But then, I should wait for the break...

Even though there was no way he was looking at me,

I just waved back at him.

That was so impolite.

But if I keep waiting, it'll just feel harder to talk to her later.

I guess at such times I should casually...

Should I ask him about it?

About who he was looking at...
