Questions

What would be a good caption for my brother's birthday?

"Happy birthday to the first friend I ever had." works for most photos.

How do I wish my elder brother?

Thank him for one specific thing he did for you, then wish him a great year.

What do I say to a younger brother?

A light teasing line and a promise of cake. "Still my favourite pest." is a safe pick.
