I've had my Spathiphyllum wallisii for about eight months now, and I'm still puzzled by its watering needs

I've had my Spathiphyllum wallisii for about eight months now, and I'm still puzzled by its watering needs. Everyone says it'll droop when thirsty, but mine seems to droop even after I water it—then perks up hours later anyway. I'm in a cold climate with dry indoor air, so maybe that's throwing things off? Does anyone else find peace lilies less dramatic than the reputation suggests, or am I just overthinking it?
