Dear friend,/ Hi Mike (name),
In this letter I'd like to tell you about how I've visited my (old?) school. Last time I was here about two years ago. Since then, lots of things have changed. I met acquaintances and even teachers that once taught me. Actually, I was surprised/amazed by the renovation of classes and the gym. Teaching staff has changed, too: the position of headteacher is now held by another person. Overall, I like changes that have happened to my (old?) school. Thanks for listening to me. Best wishes,
your name.
