If I have a time machine (homework)

I would like to meet my grand father grandfather, because he has passed away before I was borne. My mother sometimes tells me about him. When she talks about him., Sshe always says, “He was a mayor in his city. He tried to build a bridge to make people comfortable and gathered people together to build it. And he rescued a person who fell in the river. I’m very proud of him. So I want to meet and talk to/with (you can use either 'to' or 'with' but not both) him.

Hi Emily, nice work on your homework. I didn't make many corrections. I think there may be a more accurate word to use than 'comfortable' when you talk about the bridge. It is not grammatically incorrect, but it sounds strange to talk about a bridge having that effect. Perhaps you mean that people felt 'safe' having a new bridge, or that he built a bridge 'so people could live more comfortably'. If you let me know what you want to say with this sentence, I can help you rephrase it if you like - but the sentence is already grammatically correct :)

He had to built a bridge to make people at ease, and had gathered some people to build it ." He also rescued a person who fell in the river. I’m very proud of him. I want to meet and talk to with him.

Great writing!
