At age 3 you say
That's mine not yours
when someone takes your stuffed animal

At age 6 you say that's mine not yours
When someone tries to take your barbie doll

At age 10 you that's mine not yours
when someone tries to take your brand new High School Musical backpack

At age 14 you say that's mine not yours
When someone tries to take your makeup

At age 16 you say that's mine not yours when someone tries to take your iPod or cell phone

At age 20 when you are in college you say that's my half of the room, not yours

At age 24 this is my wedding dress not yours when another bride tries to but it

At age 27 the cycle starts all over again because you just had your fist children and they are twin girls
