['I have been feeling a little guilty lately... :(', 'Why is that? I Too have had some not so good feelings lately ;(', '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, and has been picking her up from work everyday', 'Oh dang, Did she eventually find a ride?', 'Yeah she had to call a taxi because her boyfriend was out of town.']
