1.Short, and large enough to read on a phone
One or two lines. Many grandfathers read at arm's length with the text size turned right up, and a long paragraph in a small font goes unread:
- Happy birthday Dadaji. Wishing you good health and a year with nothing to worry about.
- Happy birthday Nanaji. Still the person this family asks when nobody else knows the answer.
- Many happy returns. Thank you for everything you did that none of us saw at the time.
- Happy birthday Thatha. Hoping this year is kind to you and your knees.
- Happy birthday Dada. You built all of this. Today you are allowed to sit down.
- Happy birthday. Ninety percent of my patience is yours. The rest I am working on.
