Guilty

Today I made my best friends angry with me
I didn't do it on purpose
Well, basically she didn't go school today but she say she's going to tuition
So I chopped place for her
But when tuition almost start she's not here yet
So when i wanted to text her
I saw her message asking me whether i got chop place for her
I replied her saying got
But then when the class start
There are people who came late too
So my tuition teacher ask them to sit the empty place which the place I chopped for her
Then i text her again saying her place others sit already
Later when the class start I didn't check my phone
After a while I check again I received 3 message from her
She asking me come downstairs cause she wanted to gimme something
the 3rd message she already scolding me for replying her so late and making her waiting there for so long
When i reply her time it's already kinda late
So she keep scolding me
I knew she'll be damn angry at me
But I can't do anything already
I know is my fault , my wrong
The only thing I can do is apologize
But I know it won't mean anything anymore
She's still angry at me
So i sent her a message at the facebook's inbox to apologize and tell her the whole story
But until now she haven reply me yet
It's either she didn't log in to her facebook or she didn't see it or she still angry at me
Still I hope she see it soon and won't angry at me

The worse part is
My friend told me she wanted to give me my birthday present
I feel so damn guilty for making her so angry
She's been waiting for me downstairs for so long just to give me the present
But I didn't go down cause i didn't saw the message earlier
I feel so stupid for not checking my phone
If i saw the message. I'll sure will go down.
When the time I saw the message, I know she already leave
I didn't know how to face her now
I made her so angry
And it's all my FAULT
I'm so sad right now
I feel like crying already
