I am sorry, but declaring our neighborhood ‘unsafe' based on personal fearful feelings after a three days stay [maybe even another fear based opinion?] is just irresponsible. No stats. No careful observation which shows lots of passers-by of all ages [but young people especially, because of the proximity of multiple universities] walking, sitting outside, running, biking [latter one -any time of the day and night], parents and grandparents with babies and infants, couples holding hands, people going to and from work... That indicates fairly ‘safe’ to me. Within an urban setting, of course. Although we can understand and could even sympathize with individuals feeling unsafe when out of their own environment/comfort zone, it is wise to speak in personal terms [I feel…] rather than in declaratory statements. That does require recognizing own fears and their source, since nothing unpleasant [except for those pesky mosquitoes] actually happened here to these guests.
I regret to hear that the window AC units were 'noise' and that the mosquitoes took advantage of the short time when the window stayed unscreened. I am not on their menu and didn't hear anybody else even mention anything of a sort but mosquitoes have their preferred people and summer is surely their time. A friend and I have been sleeping there occasionally in different rooms/beds between guests’ stays to investigate this further. Nothing bites us. .
As for having just sheers over sun room window – that is a part of both our aesthetics and general openness approach we adopt. We, as very many of our neighbors with completely unscreened glazed porches [pictures to follow when we find the proper section for it], feel safer than ever and we actually have lived here for a long time. We are happy to see that others are not bunkering up and feel comforted by glimpsing an occasional distant contour of a neighbor or seeing a little bit of their domestic setting. That brings us closer as neighbors and I hope our visitors would pick up on that side of the view.
We do wish this guest[s] will face their fears, learn more about American neighborhoods, relax and adjust to them.
