How does one measure emotions!!!
I asked a kid how much he loved his sister, he smiled , spread his arms and I had my answer. How does one measure emotions. How does one explain ...
1) I love you..how much
2) I miss you..how much
3) Don’t hurt me ...how much
4) I care for you ..how much
5) I am in pain...how much
6) I am hurt...how much
7) I am passionate about you...how much
8) I want to hug you so tight...(i have an answer here..till you choke )
9) I am angry at your betrayal that it hurts so much...how much?

Something’s you can’t measure...that why some good emotions you need to keep expressing ....and the happiness it gives ....immense..
