John Kennedy actually said...

All of us as Americans are most appreciative of the generous reception which the people of this city and country have given us.

We have come to this open field today to join in making this a better dwelling place for men.

And I hope in this way to give some slight indication of how grateful I am to all of you for making us feel so much at home.

So I come here today to express our warm feeling of friendship, with great sincerity, to the people of this country.
