I hope you will enjoy our party or I hope it will be a pleasure for you to be part/ come to our party.

I wish I knew chemistry. I wish I was omnipotent and could change reality. [I wish I had learned chemistry in school harder. ] That's an awkward sentence you could maybe say I wish I had put more effort into learning chemistry when I was in school.

I wish I hadn't gone to that film last night. I wish I could play drums. I wish people could fly. I wish I could have helped you with your exam last week. I wish a situation of corruption in Russia would change. I wish people would stop cursing in public places. I wish you would drop the bad habit of smoking, everything is soaked with this horrible odor. I wish you would do your homework attentively.
