This is especially so, during the convid -19 endemic. 

Senoir who has retired was belittled and verbally abused now that they are not the centre piece in any family unit and and does not in many cases add value to the unit. Also due to lock down, stay at  home to be safe,  work from Home and home base learning alot of friction is generated. This is even worst if there are educatinally challenged kids in the family. .Alot of stress is generated.

Fuse is short and quarrels will happen when comments that is not deem fair is thrown at each other. In such cases there is no end ,especially where values are very different. Some loses control and ends up in sad cases where it is reported ,that father is charged with killing his children, a son stabbing his father after a heated argument at home over a detergent scoop .., a husband getting back at their wives etc. In most of this cases, they realised that it is not worth it. but because of the heat at the momment they lose control.and do the unthinkable. So for such situation, I suggest that if they at risk of losing conrol over their emotion, it is best to walk away from the situation and stay away for a few hours outside to cool down and reflect on it.. In most cases, after some reflection, they realised that  it is a very small issues that started the situations.

In any situation where you are very angry and feels like losing control over your emotions.

Just walk away. and don't answer back. It will escalate the situation.
