Meaning of idiom

[Tanya_88]

This text from song - Flowers on the wall

1. I've been hearin' you're concerned about my happiness
2. But all that thought you're givin' me is conscience I guess
3. If I were walkin' in your shoes I wouldn't worry none
While you and your friends're worryin' bout me I'm havin' lots of fun
Chorus:
Countin' flowers on the wall that don't bother me at all
Playin' solitare till dawn with a deck of fifty one
Smokin' cigarettes and watchin' Captain Kangaroo
Now don't tell me I've nothing to do
4. Last night I dressed in tails pretended I was on the town
5. As long as I can dream it's hard to slow this swinger down
So please don't give a thought to me I'm really doin' fine
You can always find me here and havin' quite a time
Chorus
It's good to see you I must go I know I look a fright
6. Anyway my eyes are not accustomed to this light
7. And my shoes are not accustomed to this hard concrete
So I must go back to my room and make my day complete
Chorus
Don't tell me I've nothing to do
