Unlucky 3

What happened to us, way back in the day.
We were best friends together we played
She came along and got added to the group.
Thats when our friendship took a drastic swoop. Three's a crowd, ones always left out. Trust me I really have no doubt. I don't recall what made us fall, but i do know that i was the cause.
I said some things that got passed back to you, and I'm telling you girl it's not even true. Whatever it was i was mad at the time.
It's not like i was trying to give you a sign.
So always remember when you make other friends,
There should never be 3 or it will surely come to an end.
