A thing that is like a once treasured toy would feel silly and pointless once discovered in the adult age, whereas the sentence is saying that things are even more significant and worthwhile
Context: "The things he used to do every day and the things that used to concern him now felt even more significant and worthwhile." Claim: "The daily routines and private family concerns of which he had once been part now felt like an old and once treasured toy that makes you smile when you find it in the back of a drawer."
Considering the context, is the claim true, false, or unknown?
