One is Company, Two’s a Crowd

I have no need for company. I’ll make it on my own.
Most anything that two can do, I can do alone.
I am no Santa Claus who needs assistance of an elf.
All tasks that need doing, I can do myself.
I never interrupt my sleep by calling on the phone.
I never argue with the choices I have made alone.
The company I give myself is by far the best.
As my best friend, I have to say I outshine all the rest!

The prompt for SOCS is “Company.”
