The fire alarm sounding when I was younger always startled me a bit (I think that goes for anybody) but I can’t say I was ever anxious of fire drills themselves. I’d say the same still goes nowadays.
Honestly, until around 6th grade I couldn’t have cared less about fire alarms. I barely ever noticed them except at school during drills/false alarms. After that my classes moved to the Middle School wing of the building which had 9845 mechanical horns. During the first fire drill of that year I thought all the different pitches sounded pretty cool (compared to the TrueAlerts in the rest of the building) so my interest started there
