some expressions The journey,this was actually one of the purposes of the trip . . . and we managed to keep all these dates, which is amazing really considering the detours we made. An old friend acted as a sort of transport organiser for everyone and the Hotel Ali in Marrakech was a good social base - I'd really recommend it, although I can't remember who runs it. Anyway, groups of friends actually joined us for three-week stints and others just linked up with us. Some, whom we hadn't met before the trip at all, tagged on for short bursts - people from the area - who just came along for the ride. But outside the major visitor areas like Toubkal we only met one other group of travellers like ourselves in the whole 96 days. 1.keep all these dates --- what's the meaning? 2.link up with us---what's the meaning of link up? 3.what's meaning of "tag on for short bursts"?

A dialogue about can That’s the bit of the can that drops down into the drink when we pull the tab. Yeah, hopefully. Sometimes the tab just breaks off. I know. Anyway the opening is scored so that it pushes in easily but doesn’t detach itself. OK, we can show that by drawing a shadow of it inside the can, like this I’ll label it scored opening. what's the meaning of "score" or "scored opening"? I did not find interpretation online.

Do you think it is insulting question? I attended a casual potluck party in Toronto a few days ago .During the party, I talked with a Philippine girl we met first time, but before she told me she was Filipino,I did not know that, I thought he was Chinese. At that moment, I said to her subconciously,"oh, you are Filipion. I see, you skin color is little lighter." The girl said," yes, my parents are Chinese, I was born in the Philippines". Actually, I didn't mean I was care about what her skin color was. I have not thought about this thing,after that, we were still talking a lot casually. I didn't think the Philippine girl felt insulted by my question in terms of her skin color, I thought it was a natural conversation. However, today, another friend who was sitting beside us in the party told me my question was not appropriate. In western countries, it was a sensitive subject I should avoid. In fact, I did not talk about her skin. what I said was just to carry on a conversation naturally in that situation. Did I do wrong?sorry, typo error. 1. an insulting question 2. he to she.
