Do you feel differently about your nieces and nephews from your siblings compared to the children of your spouse's siblings?
Do you feel closer to your nieces and nephews that are from your side of the family?
If there is a difference describe the difference and why you think it might be? Is it simply blood relation (I am not saying adopted children would be any different than biological, but what I mean is simply the difference between family and family by marriage). Or, is it just that you have a stronger bond and more communication with your own family, so in turn more interaction with the children born to your own siblings?
Or, do you feel a bond with all your nieces and nephews, including those on your spouse’s side, equally?
