Two different voices a boy and a gril if possible
"Look a street vendor! I'm so hungry! What about you?"
" Me too I'm starving! Look! He's got bagels! I really love bagels!"
"Well, I prefer hot dogs."
"So you're having a hot dog, then. And what do you want to drink with it?"
"I'll have a soda. Are you also having one?"
"No thanks. I hate soda. I just can't stand it! It's too sweet. I'll have some water".
I recorded the first person talking - if there's a male voice that wants to reply, then you can edit in Audacity and put it together!
