Buikding relationships with people online are always okay so long as you follow rules.
The ‘Hidden Rules’ for building relationships with people online are to always know who you are talking to, don't meet up with someone just because of what theyre profile picture looks like, dont send inappropriate pictures (or share any) and dont believe everything that everyone says. The internet is very dangerous and its so easy for people to pretend to be one thing than they actually are. People only show you what they want you to see.
Because ‘Sarah and her sisters has gone’ doesn’t sound right, ‘Sarah and her sisters has been’ also sounds wrong and ‘Sarah and her sisters have been’ doesn’t really make sense
