I'd like him to STOP whatever he is doing on the computer!! My chatting to others fizzled out long ago, I find it tediously dull now and if I do chat, I'm bored within 1/2 an hour and stop. So why can't he just stop without me having to ask!
He's obviously getting something out of the chatting that he wants...do you know what he is getting out of it? Who is he chatting with? Maybe he likes the attention, or flattery, or something. Is he on forums or woodworking sites, or are these sex chat sites or what?
