I have a strong belief that role models and idols are super important for people so I'd be really flattered! I'd be a little nervous but I'd try to put my best face forward.
I don't have celebrity idols, but I try to keep my role models within communicable range? Professors, friends, etc. are typically my role models, seeing as I don't know most celebrities well enough or on a personable level to label them as idols.
