how can i tell her
she konw when i'm lonesome
and she cries when i'm sad
she's up in the good time
she's down in the bed
whenver i'm discouraged
she konw just what to do
but girl she doesn't know about you
i can tell her my troubles
she makes them all seem righ
i can make up excuses
not to hold her at night
we can tell her tomorow
i tell things that i want to do
but girl how can i tell her about you
"how can i thell her about you
girl please tell me what to do
everything seems right whenever i'm with you
so girl won't you tell me
how to tell her about you
ah ah-ah ah ah ah ah"
how can i tell her i don't miss her
whenever i'm away
how can i say it's you i think of
every single night and day
but when it's easy
telling someone we're thorough
but girl help me her about you
