Alice: I’m really glad I let you talk me into going for a bike ride. It’s been years since I’ve been on a bicycle.
Sam: This is the only way to travel. You get to really see the scenery and enjoy the fresh air.
Alice: Hey, watch out! You almost dropped into that huge pothole. This asphalt is cracked and the road is all bumpy.
Sam: Thanks for the warning. Yeah, this asphalt really needs to be repaired. I’d ride on the gravel path instead, but it’s full of ruts. Oh, slow down! There’s a big dip ahead.
Alice: Whoa! I didn’t see that coming. I almost lost control on that slippery section of road. Sorry, I nearly swerved into you. Are you okay?
Sam: Yeah, I’m fine. When I suggested this route, I was sure it would be an easy ride since it’s paved all the way. I didn’t bargain for these lousy road conditions.
Alice: We’ll just have to keep our eyes open and be thankful for these crash helmets!
Sam: You won’t blame me if you go flying, will you?
Alice: Not if you break my fall.
