My husband and I have decided not to have kids

I really don't care for them and I fear they will look funky looking. you never know what you'll get with mixed kids. I like having lots of money and the freedom to do what I please. I also like being fit and trim. kids seem like a nightmare. however people keep pressuring us to have them, saying you'll regret it. Literally one mom who looks like shit and is extremely overweight, complaining about not having time for self care is telling me " I will regret it". lol I do not want her life. how do I keep ppl from annoying me about having kids????
