Because a postcard isn’t just a message—it’s a tiny time capsule. When you know the timing, you can plan the surprise. Mail a postcard from your trip, and it arrives right when your friend is having a boring Tuesday. That’s a little magic.
It also helps you manage expectations. If your mom doesn’t get your postcard for three weeks, she won’t panic—she’ll just get excited when it finally shows. And if it never shows? Well, that’s the postal lottery.
Here’s a fun thing to try: send a postcard to yourself from a trip. When it arrives weeks later, you get a surprise from your past self. It’s like getting a gift from you, but without the awkward wrapping.
