Not sure what to do.
DS18 hasn't come home yet after night out. He last messaged at midnight to say he was meeting a friend after his late work shift and that his phone was running out charge. He said 'so I may be back like 1.20' in his last message.
I'm trying to stay calm and force myself to think that the most likely scenario is that him and the friend have gone to sit in a park somewhere, but it's unlike him to be home so much later than he's told me, so I am also feeling worried.
Not sure what to do. Feels a bit silly to call police but how long do I wait?
