Happy Birthday Wishes to a Younger Brother [Sentimental to Funny]

Younger brothers look up to their older siblings for guidance and stability and warm reminders of family love. While mostly unspoken, the bond of siblings is stronger than years of silence and distance might suggest.

Nobody seems to take pride in their happy birthday wishes anymore. People send a flippant text or forget about the day entirely, which sends a completely different kind of message than the one hoped for.

No matter your age, everybody appreciates being thought of on their birthday. If you have a younger brother, let them know you care by sending a note (you can opt for something humorous if that’s more your style) and acknowledge their special day.

Happy birthday, little brother! After all these years, you’ve finally gotten older than me.
