We had my grandma's funeral back in October and it was a mistake in hindsight. I went with my OH and since my mum is on her own it was impossible not to console her. That I could deal with; she works alone and her wider circle is very small/distanced. But then all these estranged family members breaking distancing left right and centre. Even with the best intentions it's impossible to even get one word in before your great aunt that you haven't seen in 10 years has approached you from behind and wrapped an arm around you. And then in that situation, as they're crying because their sister has died, it's another thing entirely to forcibly remove them.
It was all outdoors at least but yeah, you can see why they limit the numbers etc.
