Mother's Day

In fact today by Facebook I came to know that today is Mother's Day. But somewhere I think that this is not a good signal. Why we need to express our love towards Mother, Father, etc etc on particular day? Think about festival, think about New Year, Birthday etc … all these come once a year so we need to celebrate it specially. But any relation like love of Mother and love towards mother come once a year or should we come once a year? Somewhere this is shows that we are losing our relationship bound. What do you think?
