I can work in a Thursday. If this upcoming one is alright for you, then I'll place the reservation tonight.
Age difference, when it is too great, can often be problematic. I don't mean you to begrudge him for it. I only mean to give you proper warning. To put this delicately...he is perfectly lucid sometimes, but he also has unpredictable and often violent outbursts. I do not want you to be harmed, nor do I want him to do something he will regret. It's entirely up to you if you wish to reconsider his proposal, but I did not want you to be unprepared.
