I'm afraid that the last time you and your family were over, there was an unfortunate accident. It seems that <name> broke my <broken possession>. I know that accidents happen and while there are no hard feelings, I would appreciate it if you would either replace the <broken possession> or have it repaired. Perhaps having <name> earn the cost of the repair or replacement by doing chores or extra work around the house would help teach <him/her> the importance of being careful with other people's property.
Please let me know what you prefer in terms of either replacing or repairing the broken item. Thanks for your understanding in this awkward situation.
