RY: You’re right to a certain extent. It really depends on how well it’s phrased and how gullible the person receiving the thanks is.
We’d all probably be thanking our kids in advance if it always worked and literally took away their choice to not do what asked. But most kids are smart enough to decide for themselves either way. And that’s good or else they’d be robots… Most adults are not that gullible either, except maybe the really insecure ones.
