Give me two opening sentences for a short story about an elderly couple.

Samuel and Sarah were the kind of elderly couple who seemed to have been together forever. They had been married for over 60 years and spent their days walking, gardening, and playing chess in the local park. 

The sun was shining on the picturesque park as they strolled arm in arm, sharing stories and enjoying the fresh morning air. They were happy and contented in their peaceful little bubble, completely unaware of what the future held in store for them.
