3·1 year ago- OP is from India. Check before assuming.
- Bots nowadays are rather good at generating grammatically sound sentences. The issue is usually not conveying meaning, but that doesn’t happen with OP.
- If the issue is the lack of “to” after “propose”, keep in mind that verb regency can vary even among native speakers of a language. So while “propose a girl” might look incorrect for a Canadian or American, well, it’s on the same level as a Brit complaining because you forgot the U in “colour”.
