Headcannon that post Father Material Luc and Oliver continue to foster/ adopt teens and preteens so they get pretty used to teen angst. So when all their friends kids start getting to that age they all turn to them and Luc and Oliver are all like "ya I remember when Jaz took the car for the first time..."
And then their house gets to be the safe house for all the kids that need space from their parents. And their friends are jealous that they are the "cool uncles" but they also like knowing that if their kids "run away" they will just end up at Luc and Oliver's
