Hi,there recently I got a little confused about what he said Last week on friday,he came cross me then he said“shall we meet each other on weekend?” I replied“sure” but after this weekend,he didnt give me any more information,i got mad and said“You have eaten your words” he seemed angry with me said “I don't think that we have a date before” Until now,we have no time to talk to each other,then this question still left so I wanna ask for your help? could you give me some details about the differents between western's relationship and Asia's
