Dear Professor Garreis,
I haven't seen you for a long time.
How did you spend your summer?
I spent my summer in the library and visited a long time at my
parents' house.
I am glad you had time to visit your parents. I know they liked it, too.
I hope the library time was fruitful.
Because there was a summer festival in my hometown, I went with my mother.
The name of the festival is "Yokape festival."
The "Yokape" is words to use when I ask an agreement from a partner.
Because it is the local unique thing.
Therefore other local people don't understand the dialect.
I like such a dialect.
Thank you for reading my email.
I'm waiting for you reply.
Sincerely,
Masa
