Embarrassing but still it is a chance --- People exploit such opportunity in public/social gathering either in celebrating or mourning event for their propaganda or issue. It is a pathetic moment for the host but they hardly mind it since it is ultimately a social gathering where there is no hard and fast rules to follow. Short engagement and private/side talking (in lower voice) will not hurt anyone during non-formal session (after or before main event).
