Feeling bad

I did not expect it to happen.
I did not take your effort for granted.
I know that I have disappointed you.
But I was really weak that day.
I know you have present for me to receive.
I know you put in your effort and sacrifice your only free day for me.
Sorry!
I do not know why...
I do not wish that you will feel this way.
I do care about your feelings.
I am really sorry.
Really feel bad for making you feel this way!
Sorry sister!
I hope you will forgive me... ...
