Found out a great way to permanently recognize your union the other day.
1) Put on your engagement/wedding ring after washing hair.
2) Hold the dryer in the ring-free hair, and use your ringed hand to finger-comb hair while it’s drying, taking care to expose the ring itself to the stream of very hot air.
3) Eventually, the metal will heat up so hot that it will burn the skin underneath it in a perfect circle.
Cheaper than a ring tattoo, and quicker too! Possibly not less painful, but hey — 2/3 ain’t bad.
