Invitas nullum nisi cum quo, Cotta, lavaris
et dant convivam balnea sola tibi.
mirabar quare numquam me, Cotta, vocasses:
iam scio me nudum displicuisse tibi.
You never invite anybody, Cotta, unless you have bathed with him; only the baths give you a guest. I used to wonder why you had never asked me to dinner. Now I know that you didn’t like me in the nude. (tr. David Roy Shackleton Bailey)
