You've barely known the kid a month and you've only chatted to him online. It's not that big of a deal sis.
I'm pretty sure he'll still have internet wherever he moves.
I get way attached even if its just friends...Pretty sure Ill get over it..Thanks at least he told me within a timeframe as early as now and not nearing his move date I guess...Were still hoping we can finally meet before he goes..he said.
