I Keep Seeing 3:22 on the Clock

It means it's your wedding anniversary. I know, that sounds trite and flippant. As you'll see, it is strictly the truth.

When you see 3:22, the seeing of the time reminds you that it is the numbers of your wedding anniversary. That extra mental or emotional attention is why you remember seeing 3:22. Other times, those you don't remember seeing, weren't given that extra attention.

The numbers a person remembers seeing are, generally, the numbers a person has vested with a bit more mental or emotional attention than they have with other numbers.

Thus, when you see 3:22, you give it more attention than when you see other times. And that is why you remember seeing 3:22 on the clock as often as you do.
