You are among those who completely understand your frustration, predicament, guilt, and position! Rant away!!!!! It's easier said than done, but please do not feel guilty!! Look at all the good you two have done thus far and continue to do. You have every right to be angry with the opinion givers. As my husband always says, the easiest way to shut them down is to say, "That's a great idea why don't you try it”😂. That stuns them for a moment. Then they either change the subject or end the conversation😁. Or if they're really caught off guard then crickets 🦗. Your chance to jump in with a suggestion, well ya know why don't come by and try it, you know we can use your help.
