Gruñón literally translates to "grumpy" or "grumbler." It's an endearing term often used to describe someone who is habitually irritable but perhaps also lovable.
In the song, Lupillo Rivera uses "viejo gruñón" (grumpy old man) to affectionately refer to a beloved figure, likely his father or grandfather, who has passed away. This word adds a touch of warmth and nostalgia, highlighting a complex relationship filled with both exasperation and deep affection.
Lupillo Rivera's "Como Olvida (En Vivo)" is a heartfelt journey through memory, reflecting on a life lived with pride and a deep sense of family. He starts by declaring, "con orgullo digo que soy rangers te no / ambiciono dinero soy muy feliz en la vida" [with pride I say I'm a ranger, I don't covet money, I'm very happy in life]. It's clear he values his roots, growing up "entre vargas mi cama fueron las papas y un buen costal" [among sacks, my bed was potatoes and a good sack].
The song then shifts to the profound impact of his mother, who taught him about love without words: "mi código del amor lo conocí por mi madre / aunque nunca me lo dijo mi corazón lo sentía" [I learned my code of love from my mother / although she never told me, my heart felt it]. He remembers the simple joy of a tortilla, filling the kitchen with its aroma. But the core of the song is about loss and the struggle to forget. He sings about a "viejo gruñón" [grumpy old man] who "sin avisar al cielo se escapó" [without warning escaped to heaven], and a "hermano mayor" [older brother] who "se mueve para el norte jamás regresó" [moved north and never returned]. The repeated question, "cómo olvidar?" [how to forget?], really hits you, showing how these memories, both happy and sad, are impossible to let go of.
