Dear Dad,
Wishing you a very Happy Birthday today, 26th November!
I am sure you are experiencing all these and accepting my Salutes!
I would come up with the posts which I wanted to share with you in person. 
I am sure I would take and make this as an opportunity for all the children to repay their parents on time, in terms of the trends and technologies which you neither had an opportunity nor a necessity to know !!
Bless me to accomplish the activity!!!
Miss you a lots!
