Are thigh high socks really that inappropriate lol?

I wore thigh high socks to a friends house and her mom said it was inappropriate so I took them off. For me it's not a big deal they're just socks I would wear them all day at my house but I didn't want her to say anything else about it so I took them off plus she kept staring at me like she was disappointed.
