person A: I wish my friend didn't cancel on me last minute_comma_ I was really hoping she could go with me to that special concert.
person B: That's a shame. Is there someone else who can go with you? I'm available. LOL
person A: Thanks for the offer! Yeah_comma_ she just unexpectedly told me that she had a work obligation to attend instead.
person B: I'm sure she really wanted to go. Sometimes we have to make choices we don't like. My offer still stands. 
person A: That's true. Thanks for reminding me about that.
