I'm trying to resolve an arguement my sister and I had... So if any of
you answer the right thing I will be very happy! lol...
So here are my personality traits:
Light-hearted
Down-to-earth
opinionated
Passionate
Determined
Sometimes kind of silly
Logical

OK, so based off my personality and my looks what character from a
movie do I remind you of? It can be any kind of movie.... (I just hope
someone picks the right thing so I can show my sister)
