That's great. Did your nephew also remember to check behind the dresser, open each of the drawers to measure for secret compartments, pull the bedding away from the wall, lift up the mattress, rap on walls for hollow spots, etc?
No?
Then I doubt he was a rogue with trained investigation, perception, expertise in both, and reliable talent. And neither are you.
That's the difference here with some of this discussion. A skilled adventurer probably has techniques a middle aged D&D hobbyist, much less your little nephew, doesn't have when it comes to finding traps, disarming them, effectively searching a room for valuables, and many more. Is it wrong for a player to want to leverage those rather than their own?
