The only time you can use the Cool page me line to anybody is when it's a person you don't want to contact you.
Like for instance, say you are in the local convenience store and this guy or girl walks in that you know, but are not really good friends with. This is how you use coolpage me.
Them: hey man what's up?
You: nothing how you been?
Them: Alright, where are you going?
You: you know just about to run some errands
Them: cool man we need to get together some time and hang
You: yeah thats cool, page me later, OK
Them: hell yeah, man, I'll do that
All the while you know you don't own pager, so then you high tail it outta there before he/she can ask you for the number to your non existant pager.
And that my friends is how to use the Cool, page me line
OKKKKKKKKKKK
If you have any further questions please page me
Peace
