                I’ve had a lot of heroic moments where I face a bully and
                give them a piece of my mind. Unfortunately, they’re all
                in my head. Watch this kid do a very brave, very rare
                thing: stand up for himself.

                Jake is now a junior in high school, and unsurprisingly, he’s
                doing great. Here’s an update directly from him:
            </p>

            <p class="thread__content">
                "Bullying has had a big impact on my life, but since the movie
                I’ve made a lot of friends. Recently, I have joined my high
                school football team! At first I thought they would all be
                complete jerks, but actually they are pretty cool guys and
                have helped me through a lot of situations — they stand up
                for me!
            </p>

            <p class="thread__content">
                "For other kids with autism, if you're getting bullied, try and
                tell them to stop and not give a reaction — if that doesn’t
                work, go to an adult. It might seem hard cause we can’t handle
                stress as well as other kids, but you will get through it and
                you’ll be awesome — actually you already are!
            </p>

            <p class="thread__content">
                "Bullying does not make you cool — you might think you are on
                the top of the food chain — but you’re not going to be
                there forever."

Block -> Element -> Modifier


 - Blocks devem ser INDEPENDENTES. Se dependem de um contexto
, devem ser um Element.

 - seletores de elemento não devem ser usados (idealmente falando)

 - cascading deve ser evitado (normalmente)

 - ".caps", etc

 - .thread__block OU .thread__likes+.thread__content__poster

 - thread__comments__commentbox__avatar (nesting mto avançado =S)

	- Blocks devem ser INDEPENDENTES. Se dependem de um contexto
	, devem ser um Element.

	- seletores de elemento não devem ser usados (idealmente falando)

	- cascading deve ser evitado (normalmente)

	- ".caps", etc

	- .thread__block OU .thread__likes+.thread__content__poster

	- thread__comments__commentbox__avatar (nesting mto avançado =S)
