You know what I find odd. You didn't even know how many people you'd invited until recently. You are panicking about logistics. And you say:
I’m not a particularly good cook, never mind on a barbecue.
But when people suggest someone, usually a man, is bound to tak over the bbq:
Yes there are a few men invited, but I wouldn’t let any of them take over the barbecue.
You are now also a psychic:
I am confident that these men won’t offer to barbecue.
Despite not being a particularly good cook, and in a total lather over it all:
Because I am hosting and would find it very odd to allow a guest to cook the food. I am confident that these are not the type of men who would want to take over the barbecue anyway though.
And, bizarrely, you state:
Zero alpha males will be at this barbecue - or at least none of them would ever suggest they should take over the barbecue.
I am confident that none of the men invited to this one will want to show off their manliness by taking charge of the barbecue.
You wouldn't accept their non-existent help anyway:
I don’t really want someone to do it for me. It’s just the logistics.
But you aren't a very good cook and are in a panic over how will all the meat get cooked in time, etc etc. More fortune-telling:
It ranges from very, very good friends to people I’ve only met a couple of times.
None of whom you seem confident to state, barely knowing them at all, will be capable of or interested in turning a few snags on a bbq.
I don’t really want guests cooking the food. It’s just the logistics I’m worried about.
And on it goes, countless posts putting up roadblocks to the most sensible solution of all. Accept you will need help, and that most men like to bbq.
