It’s a difficult lesson for anyone to learn, really, even for the Princess of Friendship. Life is full of thousands of random moments where anything can happen, and if you miss out on any of them not only will you never get a chance to be part of the experience, you’ll always know that you can’t be. For a pony like Twilight (and I suspect at least some people here), who has spent so much of her life without good friends, the knowledge of missing such a special and unique bonding moment is undoubtedly a painful realization, and I can easily see why she would want to recreate it or try and disprove that it happened.
Maybe the bigger part of this lesson is that while you won’t (and can’t) always be a part of everything that happens (something Pinkie Pie could undoubtedly confirm), you should always take make the most of the times you do have with others. Because the more moments you do have with those you care about, the less you’ll regret the ones that do slip you by.
The animation during this little outburst was so good. Especially when she started tearing up then wiped those tears away. That is great attention to detail.

I was getting some personal feels the more Twilight tried to ‘handle’ the situation. This just took the cake. I definitely can relate to Twilight in some frighteningly close ways.
