What if roommates always imitate the way you speak?

If your roommate always imitates your way of speaking, you should be thankful, because since he can learn your way of speaking, it proves that you are excellent and your way of speaking is very pleasing. But if you also care about your roommate learning your way of speaking, you can gently tell him to learn from others. You can tell him that you may see that others speak in a good way, or something, but you must not completely understand others. Learning from other people's examples tells us that it is counterproductive to completely imitate other people's things.
