Questions
What do you write in a birthday card for your son?
A birthday card for your son is a chance to tell him what you might not say out loud. Lead with pride and one specific thing you love about him. The strongest messages name one specific, true thing about them and say plainly how you feel — keep it short and it lands harder.
How long should a birthday message be?
One to three sentences is plenty. A short, specific line beats a long, generic paragraph — people remember the detail, not the word count.
