💡 Pro Tip: Roast with Love

When roasting Grandma or Grandpa, the secret is balance.
Keep it playful, keep it kind, and always mix humor with appreciation. They’ll laugh louder when they know it’s coming from the heart (and maybe from the grandchild they secretly spoil the most).

Laughter keeps us young — and if that’s true, Grandma and Grandpa might just live forever.
So light the candles, share the cake, and let the jokes flow. Because the best birthdays are the ones filled with love, laughter, and a little bit of gentle roasting.
