A few years back when I kept bees, a friend who is a bee keeper, came by with a buddy, also a bee keeper.
We were standing by a hive of mine and I popped of the top of the supper, you have noticed how your bees are not bothered by you and you don't have to ware a helmut or smoke. They , these guys, ran off about twenty feet, my friend said " go away for a couple weeks and come back and try that.
It's great how they learn to accept you.
Haven't had bees for a few years but cleared the snow from a bee keepers drive when he wanted to come up to his mountain place, when he tried to pay me for it, I said " Na, bring up a hive when the weather warms up. Looking forward to having them again.
