Scientists say

that tears shed

in sadness 

(bitter)

taste differently

from those spilled

in joy 

(sweet)

and sweat

due to stress

smells worse

than what's excreted

in work and in sex

though the two

are sometimes 

the same

but with you

for a change

the two 

aren't identical.

You'll always

have that letter

I sent.
