Dear you.
I thought you were a friend and for a time it was sweet to have someone to visit with.
But you are not really a friend - you use me for what little I have, criticize my differences, and are not the sort of person I care to be around.
After today, I will be distancing myself further. This is our last playdate, I will not be contacting you while my sister is here, and I doubt we will see each other in person again.
I found this image today:

I strive with all my being to be the person on the left of this diagram - you are firmly stuck into being the person on the right.
Sorry, and goodbye.
