Translation of iris in Spanish

The four of us ate dinner at this cozy place. As always, we ate meat. After desert we headed to a night club, when my wife started to feel a little dizzy. She blamed the wine, but i had a bad feeling.
We joined the mass and climbed it. The stones were a little slippery and I doubt that this place is accident free. Climbing big slippery stones was not an easy task but we managed it slowly.
Many thanks for your letter. I am delighted to tell you that I have passed my exams and am looking forward to the next year. Meanwhile I am planning a trip to Costa Rica and some places around there.
