This is despicable. Some 18-19 year old college fresher who made an honest mistake has to now live with this extreme mockery from a comedian with millions of followers. Nothing cool or funny about this. Only shameful that taunting a student equals humour and viral content.
This is a rude, inconsiderate and self-centred response. Above all: It was impulsive.
It took barely 7 mins for this guy to read the email, come up with a snarky response and send it out. (And then almost immediately screenshot it of course.)
The response was meant for internet clout at the expense of some student’s efforts.
