Jack and I have raised 5 children, now soon to be 7 granchildren, graduation parties, weddings, all kinds of family functions on our wood floors, 1000's of bodies some really big
bodies (I am not telling stories) and they have been fine. Seth and Sasha (now Silas) are the least of our worries.
Everything will be fine.
By the way the scratches that are on the floor usally have a story/memory with it and it just makes us smile.
