Why do "adults" have kids when they aint stable?

Like I honestly dont get it and this whole "generational trauma" thing is killing me literally. I got into an argument with my birth giver over freaking dishes. (Mind you I didnt put those dishes there and my dad didnt wash them because he made his friends ate all that then left the mess. so of course I left it there because Im tired of coming home from school and cleaning up only to find it messed up again the next day by the same people.)

She started complaining about having to wash dishes after coming back from work plus something else and I basically responded, "Imagine what I saw when I woke up." Im on midterm break (only two days) and who wants to do chores during break? She kept saying she’s been at work, blah blah blah. Yeah I get it shes tired but why is she taking all that out on me? Im tired too school is exhausting as hell. Shes still yelling bruh.

So I said "Why did you have kids then?" cause she said I wonder whats gonna happen when u turns 20 and move out. I already know what thatl will look like and Ill be at peace when I do because I wont have someone breathing down my neck. I think she called me lazy cause of the whole 20 thing or something im not sure. Then she told me to go upstairs before she "licks me down" (aka punch me).

This is a Caribbean household violence is pretty common I swear. "I was like so you’re gonna abuse me again? Wow not surprising." Im still laughing about it. This house is so dead to me. Also its my birthday tomorrow guys so thats fun.
