This quote remained stuck on her like a label, because Garbo had always been very reserved and had avoided all public appearances as much as it was possible.
In reality Garbo declared about her private life, that she never said, 'I want to be alone'; she only said, 'I want to be let alone'. There is a world of difference.
If compared with the fever of incessant self-promotion which seems to be present in all social spheres nowadays, when people try hard to put themselves in the limelight by all means I think Garbo's attitude was of sublime elegance.
