I have been around this old block before   I've walked into abruptly closing doors   Schooled in hard knocks, I've learned a lot   'Bout how a heart can break   I might not know what love is   But I know what it ain't      It ain't layin' in the dark and wonderin'   Why she hasn't called and now it's 2 a.m.   It ain't drivin' by her house to find her wrapped up   In the arms of your ex-best friend      It ain't bold faced lies or alibis   That cannot be explained   I might not know what love is   But I know what it ain't      You say you could show me how to love   Baby, there's one thing you can be sure of   I wouldn't treat you wrong   'Cause I've been on the hurtin' side of pain   I might not know what love is   But I know what it ain't      It ain't showin' up for dinner   With a rose and chardonnay, then drinkin' by yourself   It ain't a postcard from Hawaii sayin'   "We can still be friends, but I met someone else"      It ain't bold faced lies or alibis   That cannot be explained   I might not know what love is   But I know what it ain't      It ain't a mink coat, forty pairs of shoes   Two 14 carat anklets, on my Mastercard   It ain't walkin' in a pawn shop   Recognizing her engagement ring, she swore she lost      It ain't bold faced lies or alibis   That cannot be explained   I might not know what love is   But I know what it ain't      If you had all day, I could tell you things   That would make a grown man faint   I might not know what love is   But I know what it ain't      Yeah, I know what it ain't
