 EBONY: Yeah, yeah, I actually do that already. Every Saturday morning, we go to this little donut shop, and they each pick one, and we sit there and talk about their week. It's like five bucks total, and they love it. I just, I don't know. I got in my head tonight thinking it wasn't enough, that I wasn't enough, because I can't...

 EBONY: I mean, they might in the moment while they're young, but when they get older and they can look back and see what you did give them, they'll much appreciate donut Saturday or Donut Sunday or whatever it was over. My mom gave me this fancy car. If you want to make more money and be able to do those bigger things, that's an option too. You can do those things, but I think probably it would take more of your time and attention away from the kids and make those gifts a lot less meaningful. You know what's messed up? I heard from Donnie earlier, the guy who called about his dad having the whole second family, and I was sitting here thinking, at least my dad was there. At least he gave me his time. And then I turn around and worry I'm not giving my kids enough because I can't buy them a truck someday. Like I'm completely missing what actually mattered about my dad.
 
 LUKE: Yeah, don't worry about it. You just got got by a commercial. That's what they're designed to do, it's doing a very good job on you. So don't worry about it. You're enough for your kids. Give them as much as you can in your time and attention. Spend time with them and have those special days, and that's what they're going to remember when they get older.
