Wife is like a TV, Girlfriend is like a MOBILE. At home u watch TV, But when u go out u take ur MOBILE. Sometimes u enjoy TV, But most of the time u play with ur MOBILE. TV is free for life, But for the MOBILE, if you don't pay, the services will be terminated. TV is big, bulky and most of the time old, But the MOBILE is cute, slim, curvy and very portable. Operational costs for TV is often acceptable, But for the MOBILE it is often high and demanding. TV has a remote, MOBILE doesn't. Most importantly, MOBILE is a two-way communication (u talk and listen), But with the TV you MUST only listen (whether you want to or not). Last but not least .. TVs don't have viruses, But MOBILEs often do!
