Ds is nearly 18. He has been going to the gym for a few months now. He has tough year with smoking weed and a few mental health problems so I’ve been pleased that he is getting hooked on exercise. Tonight he took a sauna after his workout. An older man ( he thinks in his 50’s) followed him in and started chatting to him. At first my son thought he was being friendly (similar age to his dad) but then he asked my son where he lived and then asked him if he could give my a son a lift home. My son felt uncomfortable so left promptly and walked to catch his bus. My son often goes to the gym in the evening and now feel a bit anxious about this. I don’t think this is normal friendly behaviour. My son is straight and has a girlfriend and looks quite young for 18.
