Stop Freezing On Have Seen Yesterday

Exactly, that gets the point across every time. Freezing over the tense just kills your chance to practice and improve. Just say it and the rest falls into place with real use.

I see how freezing over tense can shut down speaking practice. In writing or interviews though, mixing present perfect with a specific past time like yesterday shifts the meaning and the reader rarely stops to clarify. Fixing the rule once keeps the score stable instead of leaving it open to misread.
