"
j'appartiens
Quand il me prend dans ses bras
Il me parle tout bas
literal translation would be
"when he takes me in his arms,
he talks to me all low,
i see....."
it means that when her lover takes her in his arms and talks to her in a soft whispering tone ...
she sees ....
(the next phrase will follow that she sees the life in pink)
(la vie en rose mans life in pink )
life in pink depicts a state where everything appears rosy and cheerful to you. It's about a state of bliss when everything around you is a source of joy.
