person A: I have been feeling a little guilty lately... :(
person B: Why is that? I Too have had some not so good feelings lately ;(
person A: I left my friend behind at work thinking she had a way to get home that day. I usually drive her home but she recently got into a relationship with a man_comma_ and has been picking her up from work everyday
person B: Oh dang_comma_ Did she eventually find a ride?
person A: Yeah she had to call a taxi because her boyfriend was out of town. 
person B: Hopefully she doesn't blame you. Does she?
person A: No_comma_ she forgot to let me know that she needed a ride home yesterday. We are still great friends_comma_ I just feel guilty that I didn't ask and made an assumption.
