in a Big big world

It's not a Big big thing if you leave me

I too too will miss you much

miss you much...

I can see the first leaf falling

it's all yellow and nice

It's so very cold outside

like the way I'm feeling inside

I'm a Big big girl

in a Big big world

It's not a big big thing if you leave me

but I do do feel that

I too too will miss you much

miss you much...

Outside it's now raining

and tears are falling from my eyes

why did it have to happen

why did it all have to end

I'm a big big girl

in a big big world

It's not a big big thing if you leave me

but I do do feel that

I too too will miss you much

miss you much...

I have your arms around me ooooh like fire

but when I open my eyes

you're gone...

I'm a big big girl

in a big big world

It's not a big big thing if you leave me

but I do do feel that

I too too will miss you much

miss you much...

I'm a big big girl

in a big big world

It's not a big big thing if you leave me

but I do feel I will miss you much

miss you much...'''
