You got to post at pic... Lol grammar police freepers will love it. “Whene”. And November with an i?? Dotted e? That confused me. Looks pretty “sus”. :)
It's not "whene", it's "where"—tell where you found it. here is a hole in the paper there. "Where" would be a more relevant piece of info than when, since the date of communication would be an indicator.
Also, the dot over the "e" does not mean it was meant to be an "i", since the loop of the "e" is perfectly formed. The dot could be a piece of debris.
What interested me was the cursive style of the times. We have letters in our family in which the capital "N" on November looks like that.
It's almost definitely a pencil script, and therefore waterproof, since graphite leads were manufactured as a very slightly oily metal, with the oil perhaps leached out of the wood shaft of the pencil.
