That's definitely world changing... regaining touch with one's near and dear.... The specifics of your girlfriend's case apart....Losing touch with one's own mother.. for 6 years??@!#@!#, and Facebook re-uniting them?? Unless this was a forcible separation due to a natural calamity/war... (in which case my heart-felt sympathies) anything like this is really inexcusable. I really,really find that sad if the current, or future generation would be requiring Facebook/Twitter to keep in touch with one's parents. That trivializes relationships.
