find the theme of this poem

Breath in breath out I say inside my head
Its a new day another time I get out my bed
With a smile on my face, Not a hint of dread

Open up the bathroom door
there’s my younger brother Fred
Mhm, and for breakfast, there’s banana bread

Hurry up and shower I herd mom said
That shes got a big surprise
we aihn’t seen nothing yet

I run outside right into the shed
moms got a weird hat on top of her head
It was huge and had feathers

Was she under the weather
Or just straight-up crazy
And Here came my brother
with the same hat on

No way this is real it feels to wrong
Was it Christmas or Easter
No, no holidays today
Maybe mokashwaong

I had a lump in my throat
Some might call it a frog
My feelings were having a fight
Like a cat and a dog

Was I sad or happy?
That’s the real question now
My brain was in a cajumble
And still not working well

Then the tears came rolling
I knew exactly what was happening
I had a good understanding

It was my grandmas birthday
You know the one that had died
We were throwing a big party
I didn’t get to say goodbye
