On your birthday this year, little brother, I propose we make a pact. I won’t reveal your age, so long as you don’t tell anyone that I’m even older than you!
Happy birthday, little brother! If there’s one thing you should’ve discovered from having an elder sibling like me is that we only get more awesome each year!
A little brother like you is actually a blessing in disguise… At first I thought I was unlucky to have a younger brother, but now as the years go on I feel like the luckiest big sister in the world!
