I can tell you from personal experience that it's not in your best interest to attempt to punch a man while sitting at the table.
Whilst it is a) incredibly satisfying and b) enables you to get out a lot of anger, it does c) attract an awful lot of strange looks. And if you are fortunate enough to be blessed with co-ordination, that's all there is too it. However, if grace was not a trait doled out to you at birth, I recommend you stay well away because sometimes, just sometimes, the edge of the table might come between your hand and their body. The hand and the table may connect, rather solidly and as a result of this temporary pairing your hand may feel it is necessary to double in size. And throb.
And continue hurting for hours!
Take heed of my warning
