When a friend invites me to 'Like' a page...

I ignore them. I don't have time for such nonsense.

I visit the page and without hesitation I 'Like' it... after all they are my friend.

I visit the page, see what it's about and then determine if I like it. If whatever the page is about isn't self-evident, I move on. Self-evident? If a page is promoting a product, a service, an artist, performer, etc., it must provide something for me to base my decision on or be linked to a page where I can learn or see more... otherwise, what am I liking?

None of the above describe how I handle such a request.
