INFORMAL EMAIL.
HI SANDRA:
Thank you for you email. It was nice to hear from you .I'm very happy that you coming to stay with me this weekend. Next weekend is carnival in my town, and I sure you enjoy it, we can do many fun things ,besides the weather is absolutely good like in summer.How are you going to come here by car or train? Both of them are good options but if you don't want drive the train is better because is more relaxing and only it take about two hours from Sevilla to Cadiz, while that the journey by car is more expensive, because you have that pay for petrol and the tollbooth and you can also find traffic jam on the road and that's very boring when you go alone.
I believe is better that you coming by train and I pick you up at the station if you are agree.
Looking forward to seeing you.
Best wishes.
May.
