What is he takes hours to reply should i do the same?

As an AI language model, I do not have knowledge of the context of "he takes hours to reply" such as who this person is and the nature of your relationship with him. However, as a general rule, it is advisable not to base your communication habits on someone else's. If it bothers you that he takes hours to reply, and you would like a more prompt response, communicate that to him. On the other hand, if you do not mind waiting for his response, then continue with your communication style. Ultimately, the way you communicate should be determined by your needs and preferences, rather than someone else's behavior.
