3．（2019•天津）阅读短文，按照题目要求用英语回答问题。

Haze Mabry, who has worked as a school keeper for thirteen years, walks into the school building every day and empties garbage cans, wipes down bathrooms and mops wet messes in the hallways.

Last Friday, after he arrived at the school, instead of finding garbage to clean up, he found almost 800 students lining the hallways with handmade cards, blowing noisemakers and singing a full-throated happy birthday to him. It was his 80th. As he walked the long hallway, some popped out of lime to hug him. They handed him so many cards that they filled several large boxes. Touched by their enthusiastic expression of affection. Mabry thanked them all. "They're like my children," Mabry said.

On a regular day, students at the school sometimes come up to him to say they're not feeling well or other times to tell him about something that happened at break. He knows most of the kids at the school, but can't name each one. Some of them make him know them. Like Faith, who often forgets her backpack in the cafeteria, and Lucy, who just wants a hug.

"He won't brag（夸耀）on himself, but it doesn't matter what he's doing or where he is, he will always stop what he's doing to take care of a child if that child is having a bad day. If a child approaches him, he will pause to give that child his undivided attention. He's the most loved one in this building," said Lori Gilreath, a reading teacher.

Mabry works circles around all the students, cleaning up messes others don't want to touch. He doesn't expect a lot. Mabry said he hadn't planned to do much for his milestone birthday, so he was happy the students had prepared the surprise celebration.

Over the weekend, he worked through the piles of handmade cards at his house. One card from a student stood out to him. It read: "Mr. Haze, you are my sunshine.”
