Are you two or three years apart the same age?

Yes, don't be too serious. Two or three years later, the social environment in which you live has not changed much, and the policies introduced by the society have not changed much, so you are the same age. When you are two or three years old at school, your grades will be different. But once you enter the society, you will find that it is fair and just, regardless of age. In communication, you won't feel that there is an age gap between you. I hope I can help you.
