Me and my friend made plans to spend the whole day at the spa. I ended up not going because my brother became ill and I had to pick him at school along with other little issues. My thing is if you didn't hear from me the least you could do is call , she texted me and I ended up not getting it . I didn't have time to text or call her due to my brother high temperature of 112 degrees. She mad at me and all she does is throw subs of how she can't rely on people and blah blah. I already explained to her what happen and she really don't care . Is that a friend ?
