Parenting (and childhood) is intense and unrelenting. You can’t expect parents to be on stage continuously and continue to be patient and kind. You also can’t expect a 7 year old to be happy listening to their parents talk about work for 45 minutes. Taking breaks or responsibly drinking a beer is perfectly fine and isn’t going to negatively impact the child any more than allowing them to watch some age appropriate media for the time before they eat.
I worked a precinct that was right next to a huge nursing home. One guy who was 98, came in and after getting his ballot fell down and was unresponsive. Luckily the home had their own staff join the groups that came to vote and resuscitated him and he continued exactly where he left off at tortoise pace.
Also lots of people who were not registered or at the wrong polling place but insist on voting anyways despite me patiently explaining and showing them how to solve the issue. They demand to “vote” so they get a provisional ballot that we dutifully process which likely will be rejected. All of them are certain we are stealing their ballot, or trying to keep them from voting. I always say to them, “you seem like you are someone who knows a lot about the election process and has the time, we need people like you to volunteer” while offering them the volunteering paperwork. They leave pretty quickly after that.
