For many people bees are scary. Even scarier when you throw in epi pen & bees in the same sentance...
In my house, my husband & I have an unspoken agreement...Unless it involves spending a ton of money, we each do what we want. However, if it involves allergic reactions, that may be different.
My thoughts- Personally- either find a nice outyard, not too far away OR perhaps when your step son is visiting you could cover the hive for the weekend with a moving screen or one of those nets that Dadant sells? The kind that you would use if you had to contain bees because of spraying pesticides, etc? Just a thougtht. Not ideal, but it may just be the best of both worlds. You get to have your bees at home (on the far end of your one acre, facing away from the house), and yet you are being considerate & thoughtful. Fear & love are powerful things...and a mother's love is like no other. If she is truly scared for her son's life- you are not going to win. Why upset your happy home? Good luck & let us know what happens...
If nothing else- get an outyard--beekeeping is a great hobby- it's just not for everyone.
