Something they mentioned this month
A new hobby, a show they just started, a chair that's falling apart. Something recent shows you're still paying attention, not going off facts from years ago.
An inside joke you can hold
The gifts best friends remember most are often ones nobody else would get, like a joke from a trip you took together turned into something real.
Something for the two of you
A two-player game, a picnic set, or anything you use together. It's a gift and a reason to hang out.
Keep a list so you're never starting from zero
Best-friend gifts get harder because the little things they mention get forgotten before their birthday. Kept keeps a note for each person, so this year's idea comes from something they said last month, not a rush the week before.
