<p>A very good question Marian, post 126.
Like you, I’d like clarification. Certainly the poster you quoted did not say the 30+ lives in the house, just as the poster did not say the 90+ mother lives in her house, either. Cpt only mentioned bringing something into her house.
Like you, Marian, I think a person living in a household might have more leeway about invitations than one that doesn’t live in the household.</p>
