Happy birthday to this grumpy bastard! His birthday is on Valentine's day but I'm working on this early.

Birthday dinner, He brought you the chocolates and other sweets his coworkers gave him for his birthday.

Established relationship, having a partner who will eat things you don't like. He doesn't like sweets but you have a giant sweet tooth, you can mention that he likes something you don't.

I'm an Opera lover but I'll do my part as a Kalego wingman.
