Just for fun

I'm not serious oh not me
I'm not serious anyone can see
There is no commitment
No long term husbandry
I'm not looking for something serious
I am just for fun

Just make me up
Take me up then throw me away
I am just the trash you find
Blowing on the motorway
I am of no matter no gravity or weight
If you let me go I'll simply float away into space
I don't want no commitment
I'm not looking for a serious affair
This is no kind of business
I come with no contract of care
I could be your boyfriend your girlfriend your great despair
I'm the hope you keep locked up
I'm not a someone
I'm just for fun
