Snakes bite
When I was growing up in the northern countryside my Dad gave me good advice - "if you are out waking and stand on an adders head, be sure to keep your foot on its neck until its dead. If you take your foot off too soon, it'll bite you probably harder than it might have done first time."
Remember that when our super-lax, very British way of not dealing with Covid19 properly first time round, alliows it to come back with a Vengeance (about 21 days after the those essential things called Pubs etc reopen?).
