A big hug - Could he be more pleased to see you? Ebracing evolved as a way of saying 'I love you' or 'I need you' He's trying to get closer without having to say anything. He's in touch with his emotions, Awww!
A kiss on both cheeks - Ooh la la! How French.
In France this would be the sign of respect - In England, it hints that he wants sexual intimacy.
Well he'll have to wait until he can say his 'Une deux trois...' won't he.
The bare minimum - You get a grunt or a slight nod - his hands stay in his pockets.
He wants to show he's confident and doesn't care about you, but the truth is the opposite.
