some lick to get the salt from your skin, some lick there selfs cos they are bored and can be a nerves thing but others lick just cos they love you, after sasha had tye and zac she started washing me too lol she would wash my hands and arms and if i took them away she would get upset, tye and zac give only kisses, annie will give my hand a few licks if im stroking her just to say i love you and brandi will lick any bit of your skin if it goes anywhere near her face just to say i love you and i think it makes her feel better.
