One thing I would argue about in this episode is the reasons the parents needed Lisa's help. Lynn Sr. needs her for converting measurements, something that's readily available on phone apps or even by a quick search on the web. As for Rita's case, I also found this reason to be pretty stupid for one simple reason: it's like present day, and couldn't Albert tell her when the train would arrive at the station? It's not rocket science, and it's virtually the same as if you are going to pick someone up from the airport. You're not gonna sit there for hours on end waiting for their flight to show up when it's a 4 hour journey from where they're coming from.

Your other reasons I agree with. I think Lincoln's classmates scolded him because they didn't want to get in trouble for yelling at a 4 year old.
