Those were good times

Tonight dg5 and I were reading one of his books.

"I remember when you guys bought me this book."
"You do?"
"Yeah. I couldn't even pick it up off the shelf." It's a dinosaur encyclopedia.
"How do you remember that?"
"I just do. I was like 3 or 4. Those were good times." !!!
"Really. Are these good times?"
"Yeah, but not as good."
"Why not?"
"We didn't have to work as much then."
