Most of the time, it is completely my fault when I get stung. I feel a little irritated if one of the girls follows me a long way from the hive and stings me when I remove the veil, but that rarely happens. When I open the hive, I'm wearing protective clothing to protect myself from the occasional angry lady, and to protect them from themselves. Sure, there is a sense of freedom and exhilaration when you go in "naked," but for me it isn't worth the risk of getting stung in the eye. I will even suit up when catching a swarm. 95% of the time I would be fine without it, but that other 5% needs to be respected. For example: a couple of weeks ago we had some tornadoes come through the area. The next day I was given the chance to catch a swarm. I suited up and climbed the ladder. A friend decided not to suit up because swarms are docile. When I bumped the branch to drop the bees into the bucket, several fell around him and commenced to do what angry, hungry bees tend to do. We had a group of new beek students there, and they all got a good laugh at his expense.
Bottom line: Respect the bees. Don't blame them if you get stung when you go into their house without gear on. (I am not saying that you are blaming the bees. Only suggesting that wearing gear and not getting stung is better than not wearing gear and getting stung. Captain Obvious here.) Oh, the moment you think you know what the bees are going to do, they will switch up and do something different. I've had beeks with 30 years in, tell me that. We are all learning as we go.
