Should I mix sand with topsoil for grass?

I'm curious, are you considering mixing SAND with topsoil to improve the quality of your lawn? I'd like to know, do you have a specific reason for wanting to do this? Are you hoping to address a drainage issue, improve soil aeration, or perhaps achieve some other benefit? And if so, have you researched the appropriate ratio of sand to topsoil that would be most effective for your lawn's needs? Additionally, I'm wondering if you've considered any potential drawbacks of mixing the two, such as the potential for sand to compact over time, reducing the overall quality of your soil. I'd be interested to hear your thoughts on this matter.
