Growing Up Fast

 is a Fallout 3 quest. As part of this quest, you also gain the Vault 101 Citizenship Award achievement.

Have a present
Right after being blinded as an infant you find yourself nine years into the future at your 10th birthday party. You'll be congratulated and given your Pip-Boy 3000.

Enjoy your party
You're given an objective. Enjoy the party and speak with your guests.

Walk forward a bit and you'll be greeted by Amata. This is your first real conversation, and you're given 3 possible responses. No matter which one you pick Amata will tell you to guess what she got you. In the end she gives you the comic "Grognak the Barbarian #14."

Turn right and talk to Old Lady Palmer and she'll give you a sweetroll.

Around this time your should turn around quickly to see a Mr. Handy cut the cake with a buzz saw. Butch DeLoria will get mad and demand your sweetroll. You have multiple options, some will make him fight you and others will avoid the fight, but will cost you your sweetroll.

Amata will talk to you afterward regardless of your choices.

Walk past your Dad and talk to Stanley - he'll give you a baseball cap.

You Dad will get up and go to a comm system that's just started beeping. He'll tell you to go down to the reactor room for a surprise he and Jonas have been working on.

Armed and in Charge
Your new objective is to meet Jonas in the reactor room. Head out the door your Dad just opened and turn right; you should bump into Beatrice on your way out. If you wait around after your Dad opens the door, Beatrice will walk in and talk to you. She'll give you a poem which you can read in your Pip-Boy 3000.

Turn left at the "reactor" sign head down the hall and turn right, head all the way down the stairs and enter the room. Talk to Jonas and wait for your Dad. When he gets to you he'll give you a BB gun. Follow him through the door. You'll be given a new objective. Shoot all 3 targets with the BB gun. This is pretty straightforward.

After you shoot each target once, you'll be charged with a new task: kill the radroach. No real threat here, a few well aimed shots should kill it pretty quick. To celebrate this, your Dad wants to take a picture with you, just walk beside your Dad and be blinded again.
