<Choose> tag helps to produce something random. Let's see how it works:
<choose> <!--This tag is what chooses what option to show--> <option>Option 1</option> <!--The Option tag with the probability to be either or either not be chosen--> <option>Option 2</option> </choose>
<choose> <option>User1234 likes apples</option> <option>User1234 likes grapes</option> </choose>
So, there is a 50% chance either message will appear. It will either say User1234 likes apples, or User1234 likes grapes. Let's see...
User1234 likes apples
