Had this with a junior:

J: Can you help me quickly?

M: Yeah, what’s up?

J: I don’t know how to make this thing work in twig (tpl engine, like jinja2)

M: hmm, you need to write if condition and it should work

J: yeah, but how do I do that in twig?

M: just write if condition in brackets, like you would in php

J: *writes: ‘{{ <?php if...’*

M: *screaming* No!!!
...

This guy, he freaked out, like literally jumped up and then had this look for the rest of the day, like he’s gonna kill me.
