You do not need to be an expert
If someone you love is neurodivergent, you may worry about saying the right thing. The book begins somewhere simpler: ask, "What helps you?" Their answer matters more than a general tip you have read, including one on this website.
Be clear and leave time
Say what you mean instead of relying on hints. Explain changes when you can. Give someone time to respond without filling every pause. These are small ways to make a conversation less demanding. Check what the person prefers rather than assuming they all need the same communication style.
Respect limits you cannot see
A no to a noisy gathering may be a no to the noise, not a no to the friendship. Someone can care deeply about you and still need rest or time alone. You can offer a quieter plan without making them prove that their limit is real.
Believe them before trying to fix it
The book gives particular weight to invisible struggles. "You look fine" can close a conversation just when someone is trying to be understood. Try "I believe you" or "Would you like me to listen, or help with something?" Make space for their strengths and humour, too. A person is more than what is difficult.
"Some limits are invisible. Ask, and listen."
