It depends on the birthday
Some years I want to crawl in a hole. Lol
I've always (kind of) made a big deal about my birthday, but not to the masses. Just to myself. I'll consider it my birthday week (yes, week) but won't really do anything special. I'll pamper myself a bit, relax, and spend time with my Bestie.
I do love celebrating other peoples birthdays. I like to do something special for them. Plan a party, send flowers, etc...
Worn out iPhone. Need I say more?
