Hello Dr. Armstrong. I'm very glad to see you.
I'm not good at using computer and English but I'll make an effort to catch up with you so please tell me when I make mistakes.
Now, I want to talk about making a purchase through the internet. Today we can search for and buy something without going out and it is very convenient for us when we had no time to go shopping. But this way, there are many troubles between seller and buyer. Some couldn't get their purchases though they paid and some wasn't paid though they sent what ordered. And we have to give our personal data such as address, phone number, e-mail address to the seller.
The internet is very useful and we can't do without it but we must be careful or may be put to trouble.
Thank you.
