When your neighbor looked after your place
when you were away, treat their next coffee.
When you've put off meeting a friend for six months, drop the first round of drinks in their wallet.
When you're running late for that 7PM reservation, send your table a bottle of wine.
When they're working late again, pay for their evening takeout.
When you're tired of sending another emoji
birthday text, pre-pay their next cupcake.
