['I made plans to spend time with my friend Megan today, and unfortunately, I had to reschedule yet again.', "That's unfortunate. Do you like her?", "Of course, she's my best friend.  I just feel bad that I had to bail on her for the third time in a row."]
I am sorry. Did you set up another day to hang out?
I was looking forward to spending time with my friend Megan today, but I had to put it off again because I fell ill this morning.
