I'm living in the Old Testament

I went to visit my dad Sunday night. He's building a second home on his property so he can move into it and tear down and then rebuild his main home. It's crazy. The new main home will have a gym and sauna and two offices, one with 250 degrees of views of the ocean. I can't believe we are related. It's seriously like the parables in the NT of the man who build a big house. My dad's house is being built solidly, (not on sand like the parable) but ultimately when it's all done, what will he have? A place to live that's not all that different than the current house. I'm not sure what to think. It's this huge investment in getting something customized to their taste, but it's simply not something I would invest that much money in. I can't believe how guilty I will feel sometimes when I spend an extra $15 at Ross and ijn comparison my dad is spending hordes of money on this new house. I don't really have an opinion on it yet, I'm still not sure if I think it's a good idea or not. But either way, it's happening.
