Ever been in a relationship where digging up the past is like opening Pandora's box of drama? Well, this track is essentially a PSA about the dangers of playing emotional archaeologist with your partner. The singer's basically saying "Hey, can we just... not?" when it comes to excavating old issues and rehashing ancient history. They're so over analyzing every little thing that they've lost sight of what made their relationship special in the first place. In fact, they're so desperate to preserve what's left that they'd prefer a comfortable lie to a painful truth that could destroy everything. The repeated question "How deep do you want to go?" isn't about scuba diving - it's a sarcastic plea to stop picking at emotional scabs. Sometimes, as the song suggests, ignorance really is bliss.
