Ron Weasley has done tons of brave things in his short life. Just that. Things.
It's not after his son, a three-year-old Hugo, goes up to him, and shows him with excitement what he caught on The Burrow's garden, asking him to see it up close, wearing a big smile, - because "look, Daddy, how wicked!"-, that he considers himself a bit brave.
Although he's still not so sure how many times he has to wash his hands to scrub the feel that his skin is still on direct contact with the spider. The bloody spider.
