Four couples are going to the movies. Each row holds eight seats. Bhavana and Ramesh don't want to sit next to Alia and Saurabh, and Alia and Saurabh don't want to sit next to Garima and Gaurav. On the other hand, Shahana and Sajid don't want to sit next to Bhavana and Ramesh.
How can the couples arrange themselves so that they all sit where they would like?
