The context of the following conversation is Sasha's younger brother had recently turned 21 so she decided to plan a surprise trip for his birthday.:
Sasha says My brother's 21st birthday is Saturday and my parent's want me to throw him a big party.
The friend responds I always though he was older than you, anyway do you have the decorations figured out.
Sasha responds No I don't even know where to start, when I think of parties, I think of clowns and balloons, he is my little brother after all.
The friend responds Yeh he's too old for that now, I am afraid. Let me help you, let's ask his friends what he would like.
Sasha responds No we can't let his friends know until the last minute, they will ruin the surprise.
The friend responds You might be right about that, ok so let's go to the store and just figure it out.
