Unbelievable how selfish people can be! These people need to be thought a good lesson so they can feel it on their skin what security means.
I live in an apartment building with 20 apartments and only the top floor has a roof but when it comes to replacing it or repair it, we all pay, regardless on which floor your apartment is and it's the same when a pipe needs to be replaced. We have a fund we are contributing monthly and that covers the small reparations. The big expenses are equally shared. No exception!
