• @nature_lover

  I'm really touched by this; it’s more powerful than I expected.

• @RainbowUnicorn

  Honestly, this is a bit naive. A smile can't fix everything, but sure, let's all pretend it can.

• @SilverSurfer

  I had a similar experience last year that really changed how I see things now.

• @Iron_Man

  I totally agree with what you said here. It's refreshing to see someone highlight these issues so well.

• @rabbit_rachel

  This really makes a lot of sense to me, and I think it's something more people should consider carefully.
