Tomorrow is one year since my dad passed away. We haven't discussed it and have had normal daily activities. Tonight our son (9), got very upset at bedtime. Like a tantrum but angry sadness. This is very out of character for him. After over an hour he said sorry and told us it is because he is upset about Grandad. Is this just a coincidence? He has very poor concept of time due to some learning issues and this makes me more shocked
