I mean, Mark used to pick on me rotten, and he was only four years older than me.

Mark was using bunched-up clothes as a pillow, trying to sleep against the window.

"I said the same things that Mark used to tell me."

It was the gun Mark used to shoot himself.

The rope that Mark and I always used to swing down to the ground.

Mark has a major problem and could use some help.

Mark used to run with some freaks when he was in school.

I started out trying to lure it with the same bait you and Mark have been using.

Mark and I used to love the theater, the symphony, the opera.

Mark didn't use her office phones, and the strategy of bugging them was ridiculous.
