Arthur watched Merlin clack the sticks together a number of times in a number of increasingly strange ways until he had to clap a hand over Merlin's to get him to stop.
"Forks are easier." He wasn't about to disagree with that assessment, given the option he'd eat with a fork every time, however mastering the chopsticks was a matter of pride.
And a certain amount of smugness. Arthur released Merlin's hands and took the chopsticks from him to readjust them and then stuck them back between Merlin's fingers, moving them over the wood until Arthur thought Merlin might be able to, possibly, move them without breaking anything.
