@EvelineSulman So true. I would also list contentment as an attribute that cannot be bought, one either has it or one does not.
@bibliolater As Paul McCartney put it, "Love."
To that we can add "immortality."
@diffgeom Does being the recipient of unctuous attention count as experiencing love? If it does then may be love can be bought especially with one trillion dollars.
@bibliolater I'd classify that closer to "adulation," which is very far from love as I mean here. :)
@bibliolater peace of mind by the absolute certainty that they like you not for your money.
