Haven't you heard the expression, "it's like herding cats?" (i.e., getting people to stay on topic is like herding cats.)
Honestly, I haven't, or else I forgot. It does make sense hahaha! I have heard the saying "like driving baby ducks" to water for a fun thread that attracts a lot of activity and "like baby ducks farting on a big pond" for an ineffective long-winded boring post.
Sheer boredom I suppose. Maybe just missing Lon. Honestly, I don't know. I ran across some interesting horse photos and my mind drifted off the beaten path.
I recon @Yvonne Smith has a pretty easy job cause we are all so well behaved , well maybe we get a little outta hand on games at times.
