Looking for a commercial with two children looking at each other from opposite windows

I am looking for a (insurance?) commercial.

Two small children, a girl and a boy, are looking at each other from opposite windows - you just see their eyes.

In the end the girl has another boy over.

I think it was for a life insurance or something like that.

There was an aria playing in the background.

I am from Europe (Austria), it was about 15 years ago +- I dont know if ot was played in the US for example.

Thanks in advance!

Edit: to be exact: the children are toddlers. That's why you just see their eyes looking out of their windows. The are too small to reach it completely
