Translation of airtight in Spanish

I will send you a summary of the activities from our last vacation last year, but I will be brief, so I will send only the highlights. It is best if we discuss everything, in the beginning of August.
We want the same thing which is learning, learning and learning. I hope that we can build a long relationship. It is very good for me to write to other members. Have a nice weekend and see you soon.
Well, now that we're friends, I am very happy to send you images. I would be happy if we can keep the contact for a long time. May I ask a questions: is Emily your real name or just an avatar name?
