The other day I had this thought that perhaps I should try and make other people's days better if I could(which I did on this day by complementing my mum's cooking haha). I think there's a lot of things you can do, basic pleases and thank yous go a long way but also taking an interest in people and complementing them on something they've put effort into works well.
This thread was supposed to bring some discussion and ideas about chivalry, good manners and being a gentleman....no one has yet put anything positive forward
