to the anon from yesterday who said he invites his Dad every Sunday to lunch: Please, Do It Moar Often! If he cannot live with you, then go moar often for a walk with him, sit on a bench and talk, ask him whatever you want to ask him, make him laugh, play a game of chess or other, call him on the phone moar often, and above all, hug him as much as possible and tell him you love him :)
