It's a way of mine to say just what I'm thinking
And to do the things, I really want to do
And you want to change the part of me I'm proud of
So I can't be myself, when I'm with you
[ Lyrics from: http://www.lyricsfreak.com/m/merle+haggard/i+cant+be+myself_20831794.html ]
Oh, you never liked the clothes I wear on Sunday
Just because I don't believe the way you do
But I believe the Lord knows, I'm unhappy
'Cause I can't be myself when I'm with you
I can't be myself and be what pleases you

And down deep inside, I don't believe that you want me to
And it's not my way to take so long deciding that
I can't be myself, when I'm with you
I can't be myself and be what pleases you
No, I can't be myself, when I'm with you
