The brits are a funny bunch to get along with. At tea break they amble to the canteen and sit down not saying anything. Occasionaly someone will make a (not so funny) remark and everyone will give it a muted laugh.(must be British Humor).
The only time when you will hear any long lasting conversation is when they are moaning about something, eg transport, wages, work collegues etc. (A word of advice, If you join in, as a Canadian you will be seen as making a direct attack on the British Nation, so its best to keep quiet)
