Where people and models part ways
“Sis, can you find my files?”

Say instead: “Sister, can you help me find my files?”

“Sis, what about the structure?”
Meant: I want help organizing something
May be taken as: the model may fetch protein structure data from a structural information system
Say instead: “Can you help me organize the structure of this?”
“Hey sis, is it safe?”
Meant: I want reassurance about a personal situation
May be taken as: the model may analyze safety instrumented system status or safety integrity levels

Tips
- Use 'sister' instead of 'sis' when you mean family to avoid technical misreads
- If you mean a specific technical SIS, spell out the full name on first use
- In technical contexts, capitalize SIS when you mean the acronym
- Add context like 'my sister' or 'family' to anchor the personal meaning
- Avoid 'sis' alone at the start of prompts about systems, safety, or storage
