编一段以“what have you been doing？”开头的，关于我儿子涂着红嘴唇回家的200字英文对话

A: What have you been doing? B: I was out with my friends. A: Where did you go? B: We went to the park. We played some games and had a great time. A: That sounds like fun. Did you get anything for me? B: Yes, I got something for you! Here it is! A: Wow, what is this? It looks like lipstick! B: It's a special kind of lipstick that I got for you! It's red so that it will make your lips look really nice. A: That's so sweet of you, thank you! But why do your lips look red too? Did you try it out yourself? B: Yeah, I just wanted to see how it looked on me and how it felt on my lips. But then I realized that if I put too much on then my mom would know what we were doing so I wiped off the excess before coming home.
