If I may digress to speaking about "Alice" for a moment.
I was thinking about why an English speaker would forget the rule about using 'an' instead of 'a' as the article before a word beginning with a vowel. In English it is a rather magical moment to have such a cut and dried rule, with no exceptions. Almost unheard of!
The answer lies in accents, dialects, and patterns of speech. There is a whole population of English speakers in the US that pronounce a or an as just 'uh'. It is not the difference between a airplane or an airplane, they pronounce either one as 'uh'. Remember she also argued that 'the' is always pronounced 'thuh', and never 'thee'. It is the same with the whole use of the word the. Some accents/dialects just swallow the word completely.
I think in the written example above it was done for emphasis, but it is an insight to some people who 'teach' a language that have no academic qualifications. In the end they are only communicating how they and their friends speak the language.
I don't think that is such a good idea.
