It’s very easy to forget that the cub is both eight years old, and quite young with it. He adopts language and mannerisms from YouTubers as a bolshy disguise, and can come across quite abrasively at times – but the real cub is closer to the surface than we remember sometimes.

One such reminder came last weekend while he and Lady S were staying with us. Reports came in of a man being murdered in a train not far from us, and the cub was distraught at the thought of it.

He’s generally quite wary of public transport anyway as a high-stimulus mode of transport to unfamiliar territory, and he knew that I would be travelling back from work by bus. He was, I’m told, very concerned that I would be okay – and the Ladies M and S spent a lot of time reassuring him.

Then he remembered that I’m due to visit Portsmouth shortly, and will be travelling by train. As Lady S tried to get him to settle to sleep, he remembered that we use the Glympse app to let each other know how our journeys and estimated arrival times are going.

So I have a specific request as I travel down, to use the app so that he and Lady S can see that I’m still moving and travelling. He has also been repeatedly reassured that I am careful as I travel and how and where I travel and so far he seems to be only slightly twitchy.

He’s too young to be reassured by statistics in the safety of travelling by trian, or by comparisons of the danger of crossing the road on the way to school. I’m certainly not opening the can of worms that some people may even see me as a danger while they travel: lone white male with shaven head and leather jacket? I do get looks.

So yes cub, I will be safe, and I will be there soon.
