You might be older than me but you certainly don’t look it! It seems as though you were blessed with the good genes in the family, sis! Happy birthday!
You might be growing up in age, but we’re yet to see you grow up in maturity! You still have plenty of time for that though, little sis! Happy birthday!
Isn’t it funny how when we were younger we would annoy each other and never want to hang out together, but nowadays all I wish for is that we could spend more time together!
Happy birthday from your better-looking and totally awesome younger sibling!
It can’t have been easy growing up with me, especially as I would get away with anything! Don’t feel bad though, sis, the younger sibling is always the favorite of the family!
