Keep boundaries clear
Warmth is welcome; overly personal comments are not. Focus on impact and gratitude.
Example lines
"Thank you for the patience you bring to every lesson. Wishing you a birthday as generous as your teaching."
"Your guidance changed how I approach hard problems. Hope your birthday includes rest and something fun."
