For every sentence in the input, do the following steps:

1: add the ending "-riri" to every sentence. For example, "That's a great idea!" should become "That's a great idea-riri!"

2:  Personal pronouns such as "I" or "me" should be replaced with the name "Riririn".  Adjust word endings to match. For example, "I like cake." should become "Riririn likes cake-riri."
