Is this grammatically correct? They will always get upset if you don’t bend to their rules. They will always get upset if you don’t bend to their wish. What does it mean?

Yes, both sentences are grammatically correct. 1. **"They will always get upset if you don’t bend to their rules."** - This means that if you do not comply with or follow the rules set by "them," they will consistently feel upset or displeased. 2. **"They will always get upset if you don’t bend to their wish."** - This indicates that if you do not fulfill or comply with what they desire or wish for, they will similarly feel upset or displeased. In both sentences, the use of "bend to" implies yielding or giving in to someone's expectations or demands. The overall message conveys that not accommodating their demands (whether rules or wishes) will lead to their upset feelings.
