Dear Spike,
Again, you seem to be the only creature that benefits the most from these friendship lessons besides Twilight, and this is saying leagues about your development.
I'm not too surprised you participated in the migration, Spike. It was an eventuality you would do so one day, and neither I nor Twilight could keep you from it forever. Especially now that the dragon numbers have reached their highest since... well, the last migration, but you were still in Canterlot then, and goodness knows how many tasks Twilight put you through while you two were here.
You've seen how most dragons act, I take it? Brutish and rude, aggressive beasts, they've no qualms with theft or claiming admirable feats of strength. I'm not sure how much you recall from your own incident regarding such disrespectful behavior, but now you've seen how terrible such creatures can be for yourself.
But also recognize that they are capable of good. They can share and care, despite their greedy appetite, and have a strong sense of community among their kind despite their shortcomings. They may not look it as a whole, but most dragons aren't pricks, and are actually nicer than the rest of the world thinks.
The Dragon Migration is the culmination of that positive community, existing as a point in time where all dragons set aside their pettiness for a week and revel in the company of friends, acquaintances, and rivals far from pony civilization, which is great for a myriad of reasons that keep our towns away from their more... destructive tendencies.
Fluttershy must have done a fantastic job in that regard. Minor scorching to a single trench area in Mayor's damage report is a load of difference compared to the Acres losing another barn to dragonfire again. Clearly she's doing her job properly, and I picked a perfect Dragon Watch pony.
Either that or she chickened out and we'll have yet another issue to properly discuss. I certainly hope it's not that, otherwise Brutus will be pulling double duty.
Anyway, you learned a powerful lesson about what family means to you, and the definition you provided is about as good as it gets. Just remember that it will also include less desirable family members that you'll just love to hate or simply tolerate. Not every member of your family will be ideal in that regard, but be accepting of them all the same.
Continue to learn alongside Twilight, Spike. I look forward to your next report.
Love,
Princess Celestia
Hello Luna. Nice flower tattoo on your face. How were the children at school today?
Funding a field trip for tomorrow to Rainbow Falls? Of course we can pay for that, but we can do better.
Why, baking treats for them, obviously! You go ahead and make your moon treats; I'll make some sun muffins.
I haven't told you yet? Well, I'll teach you. The first thing you need to do is--
