Remembered or forgotten?

In my past post, I wrote that it feels good to be remembered once in a while because it means that people do care about you right? Well, let me tell you, I experienced two extreme feelings that very day.

I was remembered by a kind friend on Friday noon and WAS FORGOTTEN by my sis bf's birthday at night. He forgot to fetch me to my sister's birthday and left me at my hostel till 9.30p.m. He asked someone else to fetch me but that someone forgot about me and he forgot and did not notice that I was not at the party. T____T

Why like that one????
