Footage from George H.W. Bush's funeral ceremony shows the incumbent US president and his wife Melania taking their seats in the first row. Both greeted Trump's predecessor, Barack Obama and his wife Michelle; however, the Clintons and Donald Trump seemed to ignore each other, avoiding eye contact.
Some noted that it would simply be inconvenient to shake hands across two seats occupied by the Obamas.
Other users, on the other hand, criticised Hillary and Bill for their lack of decency towards President Trump.
