My mother vowed several years ago that she would never own another pet . " They just break your heart when they die and I ca n't take it anymore . " I agree with her .

Question: What is the thing that " breaks your heart " ?
Answer: People are sad because the pets cause a virus that affects the physical heart .People love pets almost as much as people and pets often have short life spans so mostly people live longer than the pet .None of the above choices .People are upset because the valuable animal is gone and it is a loss of money value that is sad .
