Je ne suis pas jetable.
Let me remind you that we are here to create a corpus of sentences that are correct and natural. That is why we do not encourage users to contribute in a language they do not fully understand. Besides, it takes a lot of time to go through and correct sentences. The percentage of your correct French sentences is low and as such I encourage you to restrain your contributions to sentences that you are 100% sure you can translate by yourself (without translation tools).
If you want to practice sentence writing, there are other resources on the web.
