I have a buddy that when we started playing about 10-12 years ago was my equal on the court. I could out serve him but his groundies were always better than mine. When I had kids and finished grad school, he took command of our rivalry. Then he had kids and I spent more time on my tennis and he fell behind. It goes in cycles.
Now we play once a week and that is all he plays. It is mostly just an excuse to drink and socialize after a hit. It works out because he always wants to work on something specific. So usually he is working on serve and volley ... so I get to focus on returning. It all works out.
Now even though we are not close in tennis skills ... it is not about competition it is about spending time with a good friend.
