On your special day this year, I think it’s only right that you deserve an award for putting up with me as your coworker for the duration that you’ve worked here! That takes strength!
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!
I know exactly how you must feel on your birthday today since you make each and every day feel like a birthday for me! You are the most wonderful gift that keeps on giving, sweetie!
There aren’t many people I would choose to be my cousin and there are even fewer I’d choose to be my sister. Luckily, I didn’t have to choose between either with you as I was handed the 2 in 1!
We might have been each other’s biggest enemies at times as kids but as we’ve grown up, I’ve learnt to tolerate you much better! Happy birthday to you, sis!
