Does anyone else ever think back to positive moments in their life and ask the "what if" questions?

I do this pretty often.

One example is when I met my still to this day Best Friend in 8th grade English Class.. For context, I am 36 now.

I'll ask things like, "What if we didn't have the same English Class?" Or, "What if we didn't sit together in the same group?"

I'm thankful things turned out like they did, for these positive moments anyway.

Curious as to whether you think back and ask these questions or not? And I am focused on the positive events in life.
