I love you. (p<0.05)

Strictly speaking, it doesn't mean that there is 95% chance that I love a particular person. Because for a given person, I either love her or don't. 

To know the exact meaning of this statement, let's think about how we find out we love someone. We try to search within our feelings and actions to see if they satisfy the definition of love (whatever it is). However, due to the limitation of time and resource, we can't search for all actions and feelings we have had for a particular person. Therefore, we can only do a sampling. We pick up some feelings and actions from the vast sea of memory and determine whether they fit into the definition of love. So "I love you (p<0.05)" only means that there is more than 95% I have picked the correct set of actions and feelings, or in other words, there is less than 5% that I have picked the wrong one.

Sampling has probability. Loving someone does not.
