I wanted to ask about something I'' m not sure how to handle.Say you meet some people while you are on vacation and you exchange emails so you can keep in touch.You really don''t know them as you just met them on the beach or something like it.Maybe you see them twice in a week and just chat with them a bit.Then both parties go home and the 1st email you get from them is an anouncement that they would like to come and visit you for few days....Would you be comfortable with it?
