By contrast Gabriel looks for what is probably long enough to be obvious like he isn't sure what to do with his hand in response to that, other than shake--he is used to greeting exactly those sorts of persons in exactly that capacity, you see. He settles for a second returned wave, fingers rippling in a curl above his palm. "I--well. Hello."
Despite the sparsity of the greeting, he smiles, an upturned quirk at the corners of his mouth that suggests muscles in some disuse, but not averse to exercise. "I'm Gabriel--Bennet. And I haven't--exactly--I don't remember seeing you at school, but I don't--it's...it's been busy."
Oh god, conversation is exhausting. How do people do this??! "I'm a freshman," he adds, apparently unaware that to some people this is pretty much tantamount to saying 'please haze me.'
