Too much commitment, for at least the next 2 decades... I don't even know what country I'll live in in 2 years, half the time I don't know when I'll get home in the evening when I leave my apartment in the morning. I don't even own plants as I suck at keeping them alive. And got too much medical shit going on for me to pass on my genes - I'm infertile anyway, so kids would require active planning and effort.
I also never understood the appeal of a helpless flesh bundle that needs your constant attention.
If I ever find myself settle down and be in a relationship where I could imagine caring for kids together with my partner, I'd much rather choose to foster teens. But also fully content if this never happens
