I’m a dad with two boys well into their teens. When they were younger, I could make it to an occasional event during school but I missed a number of them due to meetings, schedules beyond my control and travel. After school was the same. Some evening events worked out but I wasn’t there between 3 and 5. Frankly you could say I wasn’t available between 7 AM and 6 PM most of the time. While I regretted not being able to attend events, I would not say the feeling ever made it to the point of guilt.
