This is just to say

Dear obsessive party-planning freak,

I have tied the balloons
So that they ascend
In a diagonal line
Instead of a cluster
And I have tied the streamers
So that they form an X
Instead of two parallel lines

I know now that this was not what you pictured
But you gave me very little instruction
And if you had such a specific image in mind
You probably should've done it yourself

I think the backyard looks quite nice
And you have insulted my inner artist
With your negativity

From,
your really annoyed (possibly former) friend

P.S.
I am the only one tall enough
To hang the banner
So you need me
