Friend 1 and Friend 2

Well my friend called. Called to see if I check my email and did I know that the kids had upcoming events to attend. I called her back and we talked for 45 min, like we had last talked yesterday. ???? I guess in a sense this is a true friend when you can not talk for months and nothing seems different.
On the other hand I went out with another friend (friend 2) and her friend shopping and to dinner. I guess I said something wrong or did something that pissed her off, because when she and her friend got in her car the door couldn't close before she was ranting about me. I know it was about me because her friend was facing me and the look of horror on her face as I was watching friend 2 rant told it all. I suppose friend 2's friend told her I was watching her rant because next thing friend 2 is knocking on my passenger window to lend me a CD we had talked about over dinner, she called me on my way home, later at home, and the next day. GUILT is a bitch. I chose not to talk to her until day 3. (I did return one phone call and LM letting her know I had seen that she had called.) My own guilt.
I did not say anything to her about the event and did not acknowledge her comments about "ditching her for 2 days". I am not a confrontational person and wondered over the 2 days: maybe I it was me. I know I am a very sarcastic person and make fun in a loving way. I know she has very thin skin and takes EVERYTHING to heart and is somewhat gullible. Maybe I just crossed her line. Although she does talk about people to others. I just never thought she talked about me and especially not in front of my face.
Lesson learned.
