For people on the spectrum, that may be extremely difficult.

I don't like lines.

No

Reading between the lines needs much knowledge about the cultural and linguistic background of the language where those hidden lines are readable to those in the know. Plus the subtext is often determined by slang expressions that even native speakers might fail to understand. But yes, I also sometimes wonder when people fail to read between the lines when I think it's oh so obvious. But here we use English and many are not native to it.

No, I don't remember ever having that problem. If I'm trying to communicate by giving hints rather than being direct, that's my fault.

nah if I'm not being direct and they're not getting it then that's on me
