Your Sister Cried lyrics

Well, I stared out of the windshield into the rain so light
And I turned on my dims, and somebody flashed me their brights
And I reached over and turned the radio way down low
Your sister cried all the way home
Lightening crashed, and the road shone like a mirror
A dog came out of the ditch, then he disappeared
And I remembered a conversation we once had on the phone
Your sister cried all the way home
I'll never know how you got into such a mess
Why do the bridesmaids all have to wear the same dress?
Everybody said you looked real good
But I think you looked stoned
Your sister cried all the way home
Your sister cried all the way home
Your sister cried all the way home
Your sister cried all the way home
