Do you go big on your birthdays or go low key or no key and just treat it as a normal day?

I prefer low-key or no-key birthdays.

My 50th was the day after I left my now second ex so it wasn't cause for celebration other than feeling unusually relaxed on the first full day in my then rented house (which is the one I now own).

I don't have anyone to 'celebrate' with other than my daughter (and perhaps my adult kids if one or more of them visit).
