A: There we are then, finished!
B: At last! Thanks a lot for helping me.
A: It was nothing. Really!
B: Nothing? I don't know how I'd've managed without you!
A: It's awfully kind of you to help me like this.
B: Any time! Any time! Never be afraid to ask if you need anything.
A: You too if I can do anything for you.
B' Thanks! I'll remember that.
A: Good! That's what friends are for ... to give each other a helping hand.
