Is this grammatically correct? What does it mean? Any possible rephrasing? It’d shock you to know that I’m just rehearsing. I’ve not even started yet😂

Yes, the sentence is grammatically correct. The meaning of the sentence is that the speaker is currently only practicing or going over something (like a performance, speech, or presentation), and they haven’t begun the actual performance or task yet. The emoji adds a humorous tone, indicating that the speaker finds the situation amusing or surprising. Here are a few possible rephrasings: 1. "You’d be surprised to learn that I’m only practicing right now. I haven’t even started yet! 😂" 2. "It might shock you to realize that I’m just in the rehearsal stage. I haven’t started the real thing yet! 😂" 3. "You wouldn't believe it, but I’m just going through my rehearsals. I haven’t even begun yet! 😂"
