If I was illiterate I would not be able to read warnings in many places like in bathrooms, or if the place require you to be a certain age. Something bad might happen if you don't read instruction in some labels in stores, or any other place that will be dangerous for any type of thing. It will be different because you will not be able to texts any of your friends, or ask them anything by using texts. You most likely will not be able to use any social media that is available. I could not be able to do homework. I will be most likely be bullied. I will not be able to help people that ask for help. I think this will be things that will probably happen if I was illiterate.
