The horrible little things as opposed to the marks in homework books.
A week last Thursday I was having a shower and found what I thought was a small scab on my shin. It turned out to be a tick but it had buried itself too far in to be pulled out. So off to the doc. After much grubbing around with a scalpel, he hooked it out. There followed 10 days of antibiotics and the caution to wait two weeks to see if it has given me viral encephalitis (“... but don’t worry because I’ve only seen one case in 30 years”).
So assuming it’s all clear by next Thursday, he’s going to give me the jab against the latter.
I think the moral of the story is: get the jab if you can because you won’t regret it if you discover one of the little b@@gers on you.
