I am so bad at doing that. I recently received a call from my grandmother and I did not answer it. She left a message wanting me to call her. I did not return the call, I don't even know why I didn't answer it. I just am afraid it may be bad news so I try to avoid it at all costs. The worst part about it is that I have been wanting to call her for a few months now, I just haven't and haven't returned her call either. I also do this with my friends, even when I am expecting the call. I look at it and decide to decline it.
