I hadn't thought about it from that perspective before. I have a thick skin & share my explorations in the hope of getting even just the odd tid-bit of knowledge shared from those with much more experience, or those like me that are learning, but are willing to share their knowledge. I was raised this way & I still choose to live this way at 50 years of age, it will be with me for life, I'm afraid.
This is exactly why I went from the local park to a much larger space that was 60 metres across. I was doing exactly what you said, being extra cautious about it & moving to a much bigger space to try it out. That I did not have the full picture yet of just how much space was required is a part of the learning process of figuring it out.
I see from your Avatar that you fly RC planes, yes? You would therefore presumably have a much bigger perspective & overview of the sort of space required to safely test this sort of thing out. I wrongly assumed that a 60 metre wide space would be adequate. I have already said that, but for you to continuously tell me off for it in a condescending manner is not really appreciated or helpful here. I have repeatedly said that I have learnt that this was not an adequate space to test this feature out, there's no reason or benefit to you repeating that I'm clearly in the wrong.
I am not being a snowflake or overly sensitive about this, maybe this is just a generational or cultural difference between us, but can you see how doing this repeatedly when the mistake has already been admitted is not really helpful at all? Sharing your insight & knowledge (without judgement) is helpful however & if you are willing to do that, I would be ever so grateful as I have a hunch that you are probably a gem full of knowledge that just needs to know that you can share it safely with people.
In regards of my photography & the advocacy work I do I have learnt much on forums just like this where people have freely shared their knowledge with each other. With me, I appreciate all the genuine sharing of knowledge that is offered, especially when given as constructive criticism. Constructive criticism shares what could be improved upon in a way that is not judgemental. For this particular scenario you could have chosen to word it something like this perhaps, which would have been very helpful & avoids me feeling like you are being condescending to me:
Can you see how that's a much more pleasant way to communicate a warning to somebody else?
Hoping that you & I can move beyond this, as I really do feel that you are one that has a lot to share here in this forum, if you're up for it.
