-Fair enough, but if you need cash shouldn't you be working? Name a child related necessity that you can't get without the other parent literally handing you cash. Food, bills, clothes, etc. don't require me giving you cash.
i mean.... you choose who you choose to be the parents of the child. if you knew they have a hard time in the workplace or made significantly less than you it is what it is.
but if you are not there with the child every single day, then there is occasion for all of those needs to arise and a need for cash. if you dont have the kids 7 days a week, a situation might come where they are somewhere and need food. a situation might come where they need to be transported somewhere, etc. should a parent have to call the other parent to come take the kid to get food everytime that occasion arises just because you feel some way about just giving cash in hand? that seem a bit overbearing which is weird because you all like to claim that women do this to keep a leash on you. but you seem to want to involve yourself in every transaction (like... do you seriously pay your child's mothers bills instead of just giving her part of the money? that doesn't seem awkward to you to be that involved?)
maybe that's why parents involve the system. maybe some don't want to have to wait or ask or depend on the other person to come around and "go shopping" in order to have sufficient care for the kid. maybe they'd rather just get the monthly, bimonthly payment and go on about their business.
maybe a way to feel better about it and move forward would be for people to see it how it actually is, you are giving them cash for the KID, not "giving them cash"
