Set Theory

There are only just so many ways
A day can go. Oh sure a thousand things
Can happen in the spans of single days
But at the end the total daytime brings
Only so many feelings. I can be
Happy despondent bored completely chill
Or several others, but I fail to see
The infinite variety some will
Insist on. Overall I find each day
Though all itself still falls, when weighed in all
Into a certain set of senses, that all may
Be comprehended. And therefore I call
The days a little similar although
Each moment quantumly may choose to go.
