This was Make-A-Wish Massachusetts and Rhode Island's 10,000^th wish. The organization in celebrating its 40^th anniversary this year.

“It’s very, very special,” said Stephanie Paglione, Kyle’s mom. “When Nate from Make-A-Wish told us that he was the 10,000^th wish, we were going to have this big party and if we wanted to participate in it. I asked Kyle and of course he was super excited about it.

“He was like, ‘I thought I had the worst luck, but now I have the best luck,’ with the 10,000^th wish. It’s just really, really amazing.”

The tree house was built by W.T. Rich Company of Natick and the furniture was donated Cardi’s Furniture.
