Soooo… today I'm gonna meet my boyfriend's daughter, and I'm nervous AF.

We've been dating for three months, and we're doing great! Now it's time for me to meet his 11 year old angel.

(She lives with her mom)

I don't want to ruin this day or say something totally inappropriate… (I'm like Chandler Bing. When I get nervous I start saying and doing all kind of stupid/random/nonsense things).

Please!!! I need your advice and a quick "Dos & Don'ts of Meeting Your Boyfriend's Daughter".
