If you're going to give "constructive criticism" on someone's work then don't make it out to be like you're making fun of the story and the writer. That's not constructive, it's just plain rude. Don't tell them "this story is like a two year old wrote it" just because it doesn't suit your personal tastes or if it isn't "realistic" enough for you. There are far better ways to tell someone they could work on some things and they would be much more likely to change them if you came at it the right way. The world has enough hate in it nowadays. We don't need people bringing down the creativity of others because that is where so many of us go to escape the shitty reality we live in. This is our safe haven and it's not meant to be a place for people to come in and just crush everything we worked so hard on.
