Big Brother 9: Dr Pam Spurr's body language special
Our body language guru Dr Pam Spurr takes a careful look at the sly and subtle body language signals of the housemates
Not a hot kiss by any means as Mario and Lisa kiss squarely on the lips signalling a real bond - but it's a friendly one rather than a passionate kiss. This is signalled by the fact Lisa's lips are puckered straight out in a firm, but quick, style of kissing rather than one that's relaxed and with parted lips. But the really interesting signal is the way she cups her right hand right around his lower back. You might expect her hand to be relaxed against the arm of the chair but this is a symbol of her wanting to form an unbroken circle around their moment.
