Years ago, moppety and I were wandering around Best Buy, ogling washers, dryers, refrigerators and ovens. I explained to her that the first time I ever really felt like a grown up wasn't when I graduated college. Or got my first apartment. Or graduated law school. Or got my first job out of law school. Or bought my house. The first time I felt like a grown up was when I became an expert on hot water heaters, because I needed a new one. Only grown ups care about hot water heaters. Only grown ups agonize over hot water heaters.
I suspect that only grown ups put their "dancing" icon on posts related to the replacement of their sewer line.
But I'm still doing my happy dance regardless of how adult it may be.
