Why do people look at being a SAHM as lazy ?!

Me and my husband went to dinner the other night with some friends and they asked me what I did and I told them I’m a SAHM and they gave me the weirdest look and acted funny the rest of the night and whenever I tell other people who ask me they look at me like seriously how can you not work that’s crazy .... I’ve even had people tell me it’s lazy when it’s far from it I’m constantly busy I’m barely home tbh like why can’t people just mind their own business they have their job and I have mine 😂 smh my husband wants me to take care of our child because he doesn’t want someone else raising it when our child becomes older I’ll start working but just not at the moment because the first few years are important !
