Long hair, tattoos and

ripped jeans which were anything but clean. He looked a dirty mess too. He jogged up the station platform and asked me when the next train went. I said,
    "In about three minutes."
I pointed to the electronic sign he had missed. It's overhead and people do miss seeing it if they aren't aware of them.
    "Thanks."
He stood there staring in the direction the train would come from and said nothing else.
The train arrived. An elderly woman was having difficulty alighting. He sprang to her side. Took her shopping trolley and put it on the platform and held out his arm for her to take. She looked startled but let him help and then muttered her thanks.
    "Now you get on," he told me, "I'll get this on."
And next minute I was on, the trusty trike was on.  I thanked him rather more effusively. It is really nice when other people help with that!
He actually validated his ticket and went to sit a little distance away. The person next to him looked uncomfortable but he didn't appear to notice. 
And, when we reached the city, he approached me again and asked, "You okay getting off?" 
It's easy in the city as the train is level with the platform. He went off.
    "You can never tell can you?" someone said to me watching him go.
No, you can't. 
Later in the morning I had to go into the Magistrate's Court in the city to get some documents certified. On the way in someone who looked much the same but had, if possible,  even more tattoos held a door open for me.
     "Paying me f-ing fine, need to get me a bike like yours," he said.
I thought again, "You can never tell."
