I think it's hard to say no to anybody we care for. This could be a spouse, a partner, a parent, a toddler, and a teen.
A challenge with teens is that while toddlers may quickly forget the incident, and while a spouse can rationally work through the situation in a mature manner, a teen has just enough maturity to remember it for weeks and just enough lack of maturity to wallow in resentment and a feeling of martyrdom.
That is why adults need to build the maturity and strength to be the 'adult in the house'. To follow the path that leads to a safe, healthy environment for everyone.
