Dear Jack Martinez,
I would like to pass on my thanks for agreeing to undertake the re-opening ceremony for the neighborhood park. Our neighborhood will benefit from such an asset and we were delighted that you agreed to enjoy the big day with us. Please visit us again some time soon, we would love to see you again.
Sincerely,
Csongor
