I can be really silly at times,
And I have proved being silly that day
What I told you it was just unintentional
I did not mean it by any way
So sorry uncle that I hurt you that day
I promise I will never ever say
Those words again
I am so sorry and I apologize
For everything I said!

Sorry because I mean it
Sorry because I wont repeat this
So sorry please forgive me
As I won't do this again!

Sorry to hear about the situation
I have no reasons enough to sympathize with you
Just stay strong and blessed
I am so sorry!

Sorry for that day if I did hurt you
I know that the fault was mine
Sorry for not coming to you
And accepting that I made a mistake
I am doing that now
For our sweet bond and sake
Please forgive me uncle
I promise this will not repeat again
I am sorry for everything!

So sorry to hear about this,
Life will be surely good to you in future
Please stay strong
I am sorry!

I feel terrible I know,
It was my fault and I accept
I am sorry won't repeat this
Please accept my heartfelt apology!

Sorry is an expression and emotion
I know I caused the hurt
I know I did things out of the blue
But I know that you have a heart of gold
You are so kind and you are true
Uncle please forgive me through
The mistake was mine
I am sorry for the same!
