person A: My neighbor asked me to watch over his dog. I told him he could trust me_comma_ but he escaped and ran away.
person B: That must have made you feel terrible. Were you able to find the dog?
person A: I feel so bad. I forgot to lock the gate. No_comma_ but I put up a lot of posters_comma_ so hopefully I find him before my neighbor comes back.
person B: I sincerely hope you can find him! But I bet your neighbor will understand it was just a mistake and you didn't do it on purpose.
