I think my hon. friend has not the facts quite correctly in his mind. The contributions, express or implied, from the children are exempt up to $20 a month. They are not wiped off the slate altogether. If we have a widowed mother with an independent income of $20 a month and two sons living with her who are contributing, or should contribute, to her support, either the independent income or the amount charged for the two sons is deducted from her pension.
