Lesie talks about what she likes to do when she has free time.

Simon: Hi! What's your name?

Lesie: My name is Lesie Gregory.

Simon: And do you want to tell us about your hobbies?

Lesie: Sure, I'll tell you about my hobbies.

Simon: OK. What are they?

Lesie: My first hobby is going to the gym. I go to the gym three times a week. I do floor exercises, aerobics classes, swimming and I do weight training.

Simon: Of all those things, what are your favorites? What's your favorite? What's your favorite thing to do?

Lesie: My favorite thing to do is either swimming or what they call aqua-aerobics.

Simon: Aqua-aerobics? What's that?

Lesie: Well, actually, there are different kinds of aqua-aerobics. It's just like an aerobics class but it's in a swimming pool, so there's, so you're not putting pressure on your joints when you're jumping up and down.

Simon: Ah, cool! Any other hobbies?

Lesie: Yeah, um, because it's going to be Christmas soon, I'll be able to enjoy my hobby of baking.

Simon: So what kind of things do you bake?

Lesie: Oh, well, sometimes I bake pies, like pumpkin pies or pecan pies. Pecan pies are very famous where I come from in Florida because we have pecan trees and then sometimes I do cakes, like really rich cakes like red velvet cakes, or carrot cakes, but this year I'm going to be baking cookies.

Simon: Cookies! What kind of cookies, Leslie?

Lesie: Ah, let's see this year's cookies are going to be the traditional Christmas sugar cookie, which is a big cookie in a kind of a Christmas shape, like a Christmas tree or Santa Claus with icing or some colored sugar, very yummy, and some M&M cookies with red and green M&M's.

Simon: Oh, wow! Sounds interesting! OK. I've got a question, or I've got something to ask you.

Three favorite adjectives? Soft, moist, and sweet.
