First of all, Happy Valentines Day to those that like it and celebrate it.
Second, during the years that I was single/divorced, I didn't like this day at all, just like I didn't like New Years Eve much either. Actually, during those 21 years, I didn't celebrate any holidays. Christmas was there, but the only gifts I bought were for myself and no décor.
Since I'm now married to a lady that totally enjoys all holidays and special days (Valentines Day), I celebrate them like she does. But, no candy anymore since we are both Diabetic II. A little gift, nice online card and dinner out.
