Some of my thoughts

 Exotic pets

I think people can have exotic pets as long as they are careful and not threatening to other people. This kind of pets are really interesting and a great option to the already known dogs and cats, especially for people who loves other kinds of animals, like snakes, spiders or any reptile.

Tatoos

I don't have any tatoos and I don't think I will, but tatoos shouldn't be look as something bad or intimidating but I'm not sure how to deal with extreme cases, I've seen people on internet tatooed all their body and even their eyes so, ¿what about those cases? maybe its easier not to talk about extreme cases.

"Mechoneo"

This kind of ritual is a great way of iniate a new phase of many students, but it could go very wrong and humilliating for students who don't like to be exposed at certain situations. I think old "mechoneo" wasn't the correct way to do it, it was over top, throwing all kind of disgusting substances and the worst part and the main problem I think is not being able to say no to all of those things and feel the "social" pressure, nowdays has gotten better as far I know.

Drugs

I don't have too much knowledge  about drugs but I think society will be legalizing more drugs according people acceptance for those drugs, for example marijuana is a widely known drug and it seems is becoming more common for people to do marijuana and more natural for those around. At some point people's perception about hard drugs -like cocaine- will be more natural or maybe it'll be stopped by scientific studies and somehow I think this is going to happen.
