How many books...........?

I think I ..................chocolate since I was born.

I ______ the book you lent me and it's great. I'll give it back to you when I finish it.

Bruce ______ tennis since he was a child. He ______ many trophies.

My dad always ( complain)

We ……………… each other since our school days.

I (wait) for hours so I was really glad when the bus finally (arrive).
