OP, you do realize this is a PUBLIC forum, right? That means providers AND parents have access to it. Therefore if you post something that is not in the normal range for parental requests, some providers will feel the need to say that some of us would be offended by a request like that, especially in the passive aggressive way it was delivered by asking THROUGH the child. It is not negative to state an opinion on that and what it can allude to.
What was negative was this particular quote, posted by YOU:
I'm a caregiver. That requires me to CARE for the kids. And if I can't switch up a craft on short notice to include a simple card then I'm not much of a care giver. And if I automatically jump to the conclusion that the parent is "using" me to do their job then I'm not a very nice person either.
The assumptions that you made that those who choose not to do special for their families make them “not much of a caregiver” and “not very nice people” are very insulting to those of us who work very hard and just choose to run their business a bit differently. THAT is where your thread got nasty. You set the tone of the thread and a precedent by posting that expectation on a site where both providers and parents can read it and set their OWN expectations for their caregivers. The other posters are right to call you out on that.
For what it’s worth, if your post was truly just about wanting craft ideas and only input for craft ideas, why even add the reason or the manner/tone it was asked (i.e. HINT HINT)? It’s not needed if you just want craft ideas for a birthday. So, I am guessing you weren’t totally over the moon with the way you were asked either and that’s why that’s in there. Don’t jump on others for picking up on that.
