Isby 

a cute intelligent girl with a ditsy personality. Tries to get away with everything with an innocent smile or giggle. At times she can be passive but stands up and holds her ground when it comes to issues she truly cares about. definitely a lady in the streets but a freak in the bed.

Isby is the kind of girl you want to marry.

It Should Have Been You: said with regret to a former partner after you’ve both moved on to others but you both know you should have made it work.

I know it’s been years since we split up but ISHBY, we could have made it

ISHBY

It Should Have Been You: often said with regret when seeing the One that got away; especially after not having seen them in a while, and you’ve both moved on.

Babe, I know we are both now married, but I always think about you, ISHBY, my dear friend.
