I'd say 75%+ of the drama in any rom-com is generated directly from a misunderstanding that would have been cleared up if those involved communicated like... I dunno... normal people. Person A sees Person B talking to Person C, immediately assumes they are romantically involved, runs away, overreacts, etc. Luckily, in the third act, someone explains to Person A that Person B and C had some other reason to interact. Which they would have know. If they'd asked. Like normal people.
