Dear Alex,

How time flies! Two months have passed since you went away. How are you doing? You get used to new surroundings in Texas? When will you return? You know, we are all you really miss. Richard says that he is not now worthy opponent badminton, since you went away.

I hope you took a lot of photos this time, so can you show us where you were, and all the interesting things that you saw.

Let us know when to expect you.

Yours sincerely,

Silvia
