What does growing up look like

For a few years now I've noticed a change. Regarding colors. I stopped looking for or finding preferences for certain colors. I still stick to yellows, emerald-greens and purples (mauves, for friends).

Instead, I'm very keen on fir trees. I delight in looking at them and have been itching to get them close. As much as I can. Actually, very little - with the help of a mug.

And delighting in this closeness, I sat and wondered if I had not reached maturity (there are some who are waiting for it, I still have reservations), if this certain steadfastness cannot be called that. What does maturity look like?

And I found the answer. When you order a mug, but you also buy another one, to keep it as a spare. You hide it somewhere good, so in case you break one, you can easily replace it. If that's not growing up, I don't know what is!
