Happy 3rd decade birthday.
Bestfriend doesn't come everyday. Girlfriends only made in school or college. They do not exist at workplace. You are a friend with shoulder to cry on, the one I turn too when I am in need of emotional and psycological help. No matter where the world takes us, you will always be my best girlfriend that I will treasure... and grow old together.
That is what the yellow gerbera means... a long lasting friendship from me to you..
