查了一下好像是真的，school mate :

"In 1974, my dad suffered a major heart attack. 

3 days after my father's burial, there was a knock on the door one school morning.

The gentleman said to my mom, I am Fred Trump, Donald's father. 

And my mom said, Yes, I know Donald went to the Kew Forest school. 

And Mr. Fred Trump said to my mom, I'm very sorry about Joseph's death. 

And what you don't know is, I'm still on the board of trustees at the Kew Forest school, and this morning, I let headmaster Mr. Phillip Rogers, know that from this day forward, myself, Fred Trump, out of my own pocket, is going to pay for your three children's tuition, because I don't want the kids to have to go back into the public school system.
