Yes, it does say you need a lot of light. I played with it for a while. BTW, the twin window fan that nygardener suggested is a great idea. I used one for a while - had it in the window blowing out for months, even in the rain and cool weather, until we got some horrid rain storms. The real reason I gave up on it was that I added a humidifier, but the fan seemed to suck most of the humidity out of the air. So I opted for a hotter, more humid room. I grow tropicals, so they loved it.

Missymar, If you're still building you could use what I used. 4x4 window @ $740 plus shipping from www.texascustomdoors.com when I bought it last year. It is completely obscure but it lets in a ton of light. They have other choices including ones with colored glass. Of course, if you're already past that point an entirely different window won't help you. Here is a link that might be useful: Glasscraft Decoglass

Sounds like a few possibilities- if daughter/grandkids moved in recently there must be no father on a continual basis. The boy may not understand that your house is no longer 'his' home. He may have witnessed/lived with a defiant/violent/drunk male in the past where this type of behavior is all he saw. Monkey See- Monkey Do. He may be ADHD. ADD. Fetal Alcohol Sydrome Disorder child. - 91-94% of ADHD/AUTISM is later diagnosed at early school age or adolescent age as FASD. ... It IS his mother who needs to set boundaries. Grandma already raised her kids- it is not her responsibility. Is the mother an alcoholic? Drugs? Physically or mentally abused and does not have the capacity herself to guide her children. You may not know these answers yet but dig. Ask grandma over or out for a hamburger. Discuss your worries with her and she may shed some light on the situation. Or not... It is not the child's fault, as much as it puts stress on you. Be proactive- lock your garage door. Lock your home doors. Ask a legal person if YOU may put a lock on the gate. Look at your County Clerk office tax assessment/file to see who legally put up the fence- you may be surprised to find out it is really your fence. Talk to your insurance company- they will have suggestions about how you can cover yourself. Most of these things are private and the neighbor's will not know of you trying to figure out the situation. Sometimes it DOES take a village to raise a child- especially a mentally affected child. I am blessed- I too have a connecting yard because two sisters and their husbands lived side by side. Then they were widows. I was able to know/visit the sister that previously owned my house for a year, before her death a few months ago at 100 years old... Her sister is my neighbor at 90, who is a wonderful woman. Don't dispair- there is a reason you are there. Figure out why as exhausting as it is right now. Chin up!

You’re welcome!
