Cleared

I come home after work (I work nights) 8 hours in the morning, a small (4 years) already sits on your computer is chopped. I told him:
 - Hello!
No reaction.
 - Hello, son!
The child does not respond. I began to resent:
 - Che for garbage? The mother came home from work, you can go, "hello" to say !!!
Small, not looking up from the computer responds:
 - CAN. Come.
