It is not out of place to mention that there is lot of nuisance to ground-floor residents(owners/tenants), road-side dogs cats, goats, cows entry when the common entry gate is left open negligently but for the only discomfort when climbing of stairs to top floor residents. Besides for all type of insects,rats, cats gaining access. Besides affecting privacy for easy peep through the windows by those miscreants parking their 2/4 wheelers and their pollution while the automobile engine is started/running. But usually the residents living on the top floors keep grudging and envying the ground-floor residents, who have easy access to their homes. Ultimately, for small petty things, one has to digest and cooperate with one another(others) in the neighborhood, for a peaceful and conducive living.
