He hasn't read the message as on whatsapp a blue tick comes up he's been online often so today a day later I sent "We could do next weekend if not this weekend an book one of the hotels online?
He hasn't looked at that message either he knows they're there? Why hasn't he replied if he brought up the hotel?
He's been on whatsapp a lot just not looked at the messages as the blue tick hasn't showed up.
We have each other on Twitter an that still
