Swing Set Girl Lyrics

It doesn't make any sense to me
I was in the park, almost too dark to see
i just couldn't help but stare
just me and her no one else was there

[ Lyrics from: http://www.lyricenter.com/e20259-mxpx~swing_set_girl_lyrics.html ]
She's my swing set girl
She makes my heart sing
She's my swing set girl
I love to watch her swing

I know those kinda girls don't go for guys like me
so I guess I haven't got a lot to lose
but I just can't help wondering
what's she gonna say to me
