I'm a bloke, you boofhead. That was your first mistake.
Second mistake: sure you're not covering up a typo or spelling error with your rave? Hmm?
Third mistake: Not yours, but your teachers' - if y is a vowel "in context" (as you put it), then there are SIX. Listen to yourself: There are five vowels, except when there are six!
Fourth mistake: using my dig, namely "I shall test you next time on reading carefully what is written." No prize for second place, pal.
Fifth mistake: You haven't yet thanked me for answering your question about Leng's book! Silly boy! Bad boy!
