Today is a big holiday (at least in Russia, but some other countries celebrate it too) – International Women Day. I wish all the best to all women out there.
If you are a man and you don’t know what to do on this day, then get your butt in the flower shop and get some flowers and maybe even a small present and give it to your woman. Than get some flowers for your mother and grandma. Than some for your aunt. Give best regards and smile at all the other women that you’ll see during the day. Basically, you can even accept this line of behaviour for all the other days in the year too. :)
