I am the only being whose doom No tongue would ask no eye would mourn I never caused a though of gloom A smile of joy sinve I was born In secret pleasure - secret tears This changeful life has slipped away As friendless after eighteen years As lone as on my natal day There have been times I cannot hide There have been times when this was drear When my sad soul forgot its pride And longed for one to love me here But those were in the early glow Of feeling since subdued by care And they have died so long ago I hardly now believe they were First melted off the hope of youth Then Fancy's rainbow fast withdrew And then experience told me trutn In mortal bosoms never grew I was grief enough to think mankind All hollow servile insincere But worse to trust to my own mind And find the same corruption there who did this?anyone konws?
