Birthdays can be low-key and surprisingly nice.
A colleague returned from Hawaii and brought me chocolate covered macadamia nuts for helping her out while she was away. (mm, what a tasty birthday treat!)
Upon finishing my grocery shopping, when the cashier innocently asked how my day was, I said, ‘Fabulous, it’s my birthday!’ He decided not to charge me for the $4 mini rose bush. It was unexpected and appreciated.
