Some students say they feel the campus is returning to normal.

“People don’t care as much as they did before. At last they are not sad,” Phil T. Telfeyan ’05 said.

Telfeyan said his parents are not overly concerned about his safety in Cambridge.

“They called the day of the attack and I called them. We all kind of felt safe the whole time, telling ourselves the big attack had already happened,” he said.

Others say they have not been able to return to their normal routine after the attacks.

“I’m very emotional about it,” Ryan Roark `04 said. “Everyone keeps on saying life has to go on, but I don’t know. I guess its hard to read the stories about it. I just got to a point where I couldn’t take it anymore.”

Roark said her parents are not too worried about her safety, although her grandmother is.

“I don’t believe there is a chance I’ll be physically injured. When it first happened, it felt like the one thing that was bedrock was taken away. My worry isn’t a bomb will be dropped on Harvard,” Roark said.

While recognizing the kindness and concern of students, Lewis tells parents in his letter that an atmosphere of tolerance is essential.

The United Ministry has made their own statement on prejudice, condemning violence aimed at Muslims in an advertisement in yesterday’s Crimson.

Lewis says he choose to speak about Sept. 11 in his morning address to Memorial Church after writing an opinion piece for The Crimson entitled “Things to Think About.”

“That [op-ed piece] started me thinking about the purpose of education.

That is how I came to address that subject in morning prayer,” Lewis said.

This was a prayer. This is not political. I’m not going to analyze it.”

Lewis was asked to speak at Morning Chapel months ago, though another impromptu speaker last week was President Laurence H. Summers.
