For me the difference between the two “my friend” and “a friend of mine” is in the first one you will reveal the name of the person and example is “Hi, this is my friend, Valentin.” while the other one is you do not have to reveal the name of the person for example “According to a friend of mine you will go on vaction next week."

A Thundershower

Today's early morning I got a heavy thundershower. I went out to have a walk for exercise on a new street with my husband, the street was very quiet and I just found a father and his son reading Chinese ancient poems beside the street. the sun rose up but I found some clounds came from south-west. Suddently，a big raindrop dropped on my arm, I immediately knew a heavy thundershower would come, and I shouted to my husband to run home, but it was late, the rain dropped down like waterfall!

 

Correction:  Early this morning we got a heavy thundershower and as the sun rose up me and my hubby decided to take a walk on this new street.  We observed that it was very quite and solemn.  While walking we found beside the street a father and son reading a Chinese ancient poems and suddenly there was a raindrop that I felt on my arm.  I told my hubby that it will rain again soon and to run home as fast as we can.  But it was too late we we're caught by the heavy rain.

 

After taking long exams I usually go and watch a relaxing movie like “The Notebook”.
