Sue? Oh lovie, your answer did not "suck"!
I think, if you forgive me for presuming? Is what you meant, that you cannot "hold" an e mail, you can't finger the edges lovingly...you can't sleep with it under your pillow. You cannot sniff the paper and smell the scent (or imagine the scent) of your loved one actually there.
There is something, just very romantic, about ink and paper...smiling, but if I didn't think so? I doubt I'd attempt poetry.
(Oh...and always send an empty page addressed to self...smile..an empty page? BEGS AN ANSWER...)<--serenity's helpful hint It might not be the answer you'd like, but it all looks good on pretty paper...
Hugs, both of you.
