Translation of souvenir in Spanish

I hope you you had a successful week in Dortmund. Because of the bad weather at the last moment I could not get on my flight to Dusseldorf and I have stayed home. I was afraid to fly.
I have began to learn English. I like to swim and to dive, because I lived near the beach while I lived in Miami. It is not similar to any other sport. But this week have not been yet to the pool.
In school, we now are learning the grammar part, more specifically, the participles and so on. I understand it at all, but the conjugations, boy they are tough. A lot of patience is needed.
