I am thankful for laughter
Laughing is involuntary, which is what makes it interesting — it's one of the few pleasures you can't fake your way into alone. Real laughter usually needs another person and a surprise.
Which is why it thins out in busy years. Nothing in a full calendar produces surprise; every hour is scheduled to go the way it goes. Laughter needs slack in the system.
It's also the most reliable read on a relationship. The people you laugh with easily tend to be the ones you can say hard things to.
Who made you laugh most recently? It's probably been longer than you'd guess.
