      Last year, we had a nice holiday. My friend and I went to the seaside for a month. I had been to the seaside several times before, but this was the first time for my friend. Naturally, it was the great event for him. Finally, the day came. It was a fine morning. We got up very early because we wanted to leave home after breakfast. We made the journey by car. We reached the seaside at noon. We spent many hours on the beach. We enjoyed making castles and channels in the sand. People said we ought to spend at least a few weeks at the seaside. If we could stay longer, so much the better. 

How long did the writer and his friend spend at the seaside?
