Personally, I'd go for Pajamas.  But, I do love me a lovely pair of pajamas.
 
I get enthralled with little plush things on occasion, but I find they don't hold my interest for very long - except in the case of Berthold, my hippo.  I LOVE Berthold.
 
Somehow, an indulgence in one of the fine botique choclatiers would make me happy.  
Vosges is one that I adore, but there are others to explore. 
 
But, overall, I'm not a big fan of Valentines Day.  I prefer little lovey surprises throughout the year for no other reason than pure love.
