Lyric discussion by RayCee 

Cover art for Fanny (Be Tender with My Love) lyrics by Bee Gees

At the beginning of the song the man mentions he is unsure of the lady's commitment. Sometimes it seems good but at other times as if she doesn't want his love. He says with mutual love it will work out well and reminds her of her promise to always love him. For most of of the song the man reassures the woman of the depth, quality and enduring nature of his love. He also explains he is sensitive and his heart can be broken easily.
