[Verse 1]
G                           C
I saw you flash a smile
F                                       G

G                                       C
You wanted so much more
F                                       G
than casual conversation

I swear I caught a look
F                                       G
Before you turned away
G                                       C
Now I don’t see the point
F                                       G
resisting your temptation
