RE: random remembered

You could use some Self in your AIML like:

<category>
    <pattern>where * live</pattern>
    <template>
        <random>
            <li I like <self>var country = random("USA", "Canada", "Mexico"); #self.like =+ country; country</self></li> 
            <li I do not like <self>var country = random("USA", "Canada", "Mexico"); #self.like =- country; country</self></li>
        </random>
    </template>
</category>
