what to do when a Mom Or Dad ask you to talk with their child about sex because they can't do it (they don't know what to say)?

I assume this is someone I care about doing the asking?

I would tell them I would be happy to give them some tips (if their kids are no older than mine) or to look for a helpful book, but that the actual parenting is THEIR job.

Help them figure out what to say and have them do it.

You teach Mom and Dad what to say and why its important the child hears it from them.

Tell them about sex ed. Thier child is going to learn about it eventually

Tell them no.

Why can't anyone say No anymore?

It depends on your relationship to the Mom or Dad and the child.

I tell them to take responsibility for their own children.

I point out to them that it's on them to figure out how to talk to their children, they should be talking to their children throughout their lives from infancy onwards (rather than 'The Talk' once they're in their teens) so it's something they get accustomed to talking about over time. There are resources to help parents teach their children, including sex ed to ensure they know facts.

Only if they show me the receipt from their sterilization.

Tell them that's their job and eff off.

Tell them to grow up and parent their own kid.
