What perfume do you use?

[dr. d]

yes or it is because of the scent it is somewhat light aquatic which tends to dissipate easily.

also, there's olfactory fatigue.
the sensation of odor weakens considerably, after a few minutes of continuous exposure.

for example,
upon entering a restoran, the odor of delicious food is quite noticeable sometimes.
but after a few minutes sitting there, one hardly notices the odor anymore.
