This can be defined in so many different ways. But I'm pretty sure today sums it up pretty nicely.
When you forget to take underwear to the gym and end up going commando all day long BUT remember to leave a pick-me-up note for your daughter before school, then that's love. There are priorities in life, and evidently underwear is not one of them.
(And if my friends and family are reading this, I'm very sorry to have traumatized you with this mental image.)
