you lay on the couch napping as your brothers friends all stroll in to join the party outside. One of your brother's friends happen to lays eyes on you.

"Who's this little squirt?" He comments.

"Hm? Oh her, that's my sister" your brother smiles.

They all comment on him never mentioning you around them. They seemed confused.

As your brothers friends headed outside one stayed back and observed you as you slept. He stayed there for a few minutes before heading out to the party.
