history: I was on one of my social media sites and ignored a message from one of my friends who said she really needed someone to go with her to an appointment for her mom so she didn't have to sit by herself in waiting room while her mom was in the back talking with doctor. Come to find out her mom had cancer and my friend just wanted me there for support. Ignored my friends message on one of my social media sites that just wanted support from me after finding out her mom had cancer.  That's unfortunate to hear. It seems like everyone lost that day.
current: Yes, indeed. Something that still bothers me to this day.
next: I am sorry. Hopefully you can make it up to your friend.
