There are lots of good things about summer: cold drinks, linen trousers, ice creams (lime Calippo, please), days that don't disappear into a frigid abyss at 4.30pm, and barbecues. But there are also some downsides. Downsides that include carcinogenic sausages and guys who insist on taking their shirts off whenever and wherever they feel like it just because it's above 15℃.
Conor McGregor is one of those guys.
Because of course he is.
A trash-talking, Gucci-draped, cockerel of a man, it's no real surprise to see McGregor as the shirtless centre of attention during a weekend stop-off in L.A - this is a man who has his own name tattooed on his abdomen after all - but that doesn't excuse him from committing the least considerate style move of summer... and that's without even going into the white chino shorts (don't buy white chino shorts).
The scourge of public spaces during warm weather, the type of guy who goes sans shirt anywhere except the beach or the pool is the same one who has loud, 20 minute phone conversations on the bus, or jumps the queue at the bar even though he knows (he definitely knows) that you were there before him. That is to say he either knows everyone is a bit grossed out by his sweaty back and doesn't care, or that he's totally oblivious. Neither of which are acceptable stances.
Even if, like McGregor, you are in prime shape and as hairless as a young sea lion, it's important - vital, in fact - to remember that absolutely no one wants to see sweaty armpits, sunburned necks or a great slab of 'Bacne' when they're out enjoying the fickle and fleeting pleasures of summer.
T-shirts aren't exactly restrictive, so just keep one on when you're out there.
