Time to say goodbye

Goodbye red brick buildings,
I will hold you in my memories.
Goodbye green yellow cactus,
I will miss you on my way.

My time has come and I must go,
With a heavy heart I will depart.
A tear rolls down my eye,
Questioning me, 'Should I?'

The new horizon calls on me,
Enticing me with new promises.
I am happy but I am sad,
Is there a way I can stay?
