Hi Robynne,
Thank you for your wonderful comment. I agree Skype would be also a good alternative for face-to-face communication. As it is pretty much the same thing, but in virtual way. Like you said, yeah, we can express our problems in detail if we can communicate face-to-face (either in Skype or in real). However, real face-to-face communication is the best way, being actually present to talk with someone, and having a conversation virtually does have some difference. 🙂
