Where has my life gone?

I seriously think I'm losing my mind.

Seriously.

Since my son has turned the age of 4 my days go like this:

Little Man: Mom! Sissy hit me!
Me: I'm sorry, Lila, tell your brother you are sorry!
Lila: Sorry bwother

LM: Mom!
Me: (trying to concentrate on something or doing something that needs to be done so I tune him out)
LM: MOOOOMMM!
Me: (continuing)
LM: MOM!
Me: Whaaaattt?
LM: Sissy is getting into (insert something that a child gets into all the time)
Me: ARG!

LM: Mom, where are we going?
Me: Gotta pick up aunt Manda
LM: Why?
Me: Because she just got off of work
LM: Why?
Me: Because she did.
LM: What kind of work?
Me: Seriously what happened to my life?

I need a job.

Seriously.
