Common Themes in Sgt. Pepper's songs | Fab Forum | The Beatles Bible

I was listening to Sgt. Pepper on a road trip and I noticed a theme with a lot of songs. Several of the songs on Sgt. Pepper kinda have a theme of things that happen life. The tracks I noitced this with are With A Little Help From My Friends , Getting Better , Fixing A Hole , She’s Leaving Home , When I sixty four, Lovely Rita , Good Morning Good Morning , and A Day In The Life . I just wanna know if anyone else noticed this theme or if it’s just me over analysing the lyrics to songs. I think songs can and should be able to be interpreted in many different ways.
