Dear Aragorn,
Let me get this straight.
You abandoned the Ringbearer, and let him go to Mordor alone. You let Frodo and Sam go to Mordor, alone. Why exactly did you go on this quest in the first place? Oh yes, it was to guide Frodo to Mordor. That worked out brilliantly, didn't it? And why did you abandon him? To chase after Pippin and Merry, who have probably already been killed horribly by orcs. And let's face it, the only reason they joined the Fellowship in the first place was to provide some comic relief.
So, to recap: You let Frodo, the Ringbearer and most important member of the Fellowship, go to Mordor unaccompanied except for a gardener with a potato obsession. Instead, you have gone running after the two least important members of the Fellowship.
Sweet Eru, boy, what were you thinking?
Elrond Half-Elven, Lord of Rivendell

Dear Elrond,
It sounds a lot less noble and kingly when you say it.
Aragorn II Elessar

Dear Ada,
We have just run into some more silly humans. These ones were led by Eomer of Rohan, who looked remarkably like an aardvark. He tried to kill Gimli, but I stopped him. He gave us horses and told us to go look at dead uruk-hai in case Pippin and Merry had somehow ended up there. We went and looked, at first it seemed like they had been killed, but then Aragorn found some rope. For some reason, this led him to believe that they were in Fangorn Forest, so now we have to go into a scary dark wood. The trees are angry.
Your loving son,
Legolas

Dear Legolas,
Take care among the trees of Fangorn, for that forest is old. Very old. Full of memory… and anger. Do try to keep out of trouble in Rohan. I know it is hard for you.
Your loving father,
Thranduil
