They left their front door open due to warm weather?! Have these people ever hard of a screen door ... a window unit air conditioner ... an electric fan?
ENGLAND TEMPS:
In the summer, it can be as hot as 32°C (90°F) but mostly the temperature only reaches 26°C. The average high in London from June through August is around 21°C (70°F) and the average low is around 12°C (51°F)

Too bad these infants have idiots for parents. This is a “utopian healthcare” country. Hopefully they’ll survive the blood loss while in the waiting room.
It’s rare for English homes to have screen doors, and even rarer for them to have air conditioning. Very hot and/or humid weather is too uncommon to warrant it.
