Today was the day of the presentation at the lecture.

I spent an hour presenting the 40-page English document I created in English.

As a rule, university lectures are given in English, so unless you do thorough preparation, you will have no idea what to expect, but, well, you can manage this if you put in the time.

However, English presentation is proportional to the amount of practice and the day's conditions.

I say

"Today's English is slippery."

-----

When I'm not in good shape, I feel like I speak with good phrases and grammar but slurred speech (which is incorrect).

When I'm in bad form, I'm in terrible shape.

Verbs and nouns may be used reversely, or past and future tenses may be mixed.

It's like multiple English words are slipping over the ice in a bullshit way.

I can feel the other me, who is different from the one speaking, looking at me with dismay, saying, 'What a disgraceful, shabby presentation you are making.

Conclusion: Today's presentation was brilliantly slippery
