We bought random sets of board games for our young kids, long ago.
Here's one game we seldom played when the kids were young: Hens and Chicks. It's a game where you try to remove round pegs without jostling the other pegs on the board -- you lose your turn if the spring-loaded pusher moves in.
When the kids were little, we barely touched these games. But now, they're a staple of the weekly Date Nights my daughters and I have set up for ourselves. Boggle, Othello, Set, Connect 4, Jenga, and Hens and Chicks: they've all found their way off our shelves and onto the dining room table.
Whooda thunk that these kid's games would become the center of our grown-up gatherings? But after all those years of letting the games gather dust, now I'm glad we had them sitting by, ready for use. Score!
