4.d3 in the two knights

I like to play blitz. But I don't like to play the blitz I get when people play 4.d3 to my two knights defence. I want to kill myself when I see this move. How do I liven the game up after that? Anything speculative with an explanation of why it could work will be appreciated.

If I am not wrong, 1. d3 is Mieses Opening, so maybe you can find some games that have strategies against that opening. Otherwise, I don't know. However, 4.d3 could include the Italian Giuocomo Pianissimo.
