I found them(?) on the vastness of Internet. I liked these stories. I'm frustrated a bit that my English variant (?) isn't perfect. Do you see even one mistake? -- I would be eager to hear any advice.

I'm walking home. Suddenly, I noticed an notice on the door of the entrance hall,

"Dear friends, Today at about 9.20 somewhere around here 120rub. was lost. If someone has found it, please, bring it to flat number 76, to Antonina Pertovna. Her pension is 1640rub."

I'm counting 120rub., looking up and calling. An old lady wearing an apron  opens the door. At once she sees me, this stranger bringing her banknotes. She starts to cuddle me, and to lament, and there were tears of happiness in her eyes. She told me that she had gone out to buy flour, returned, pulled her keys out of her pocket and, probably dropped the money. But, she refused to take the money. It turned out that I was the sixth who "has found" granny's money. I love that people are so kind and generous! 

In trade center I couldn't help overhearing part of an old couple's conversation. The old man had glanced at his wife and said:"Olya, you know, we done it, we grew old together.

A long time ago there was a real storm like there is today(?). At my workplace I was told that someone was hanging around my car. I bolted outside. I didn't notice any changes, except a hatch(window? door?) , Someone closed it more tightly so it wouldn't be damaged.

(You can write in Russian too and I'll be able to correct the english better, I'll understand your meaning more clearly in some places)
