I wish that in this moment that's so challenging for parents, someone would launch a 'spare the parents' campaign for non essential asks. No, you cannot ask parents during a pandemic if they will 'chat to your friend for half an hour about marketing'. You cannot suggest that they run a virtual happy hour. Do not add them to meetings unless absolutely essential. These are not things that are easy to say no to, so there needs to be like a marketing campaign to tell the rest of everyone that no, this is not ok.
