How can I write following in a formal way?
- It will help you when you are in need.
- It will help you when it is required.
- It will help you when needed.
- It will help you when you required to be helped.
- It will help you when you are required to do such task.
A person is denying to perform a task/job on computer and insisting that he only needs to do it for few days and then the job/task will be no more required so i do the job for him. While I am going to request him to do it himself because he may require to do the same due to any reason in future and doing so will make him know how to do that job.
Now i need a formal statement to communicate my concerns to him.
