My dad is that parent on the sideline who 'encourages' during matches with an aggressive angry tone. He probably doesn't mean to sound aggressive but he really does.
When my DB was young and played, we had to listen to it all the time. We have talked about it as adults and he knows we all hated it.
Now me and Dsiblings have children that play. I never give him details of matches so he can't come. He found out yesterday about a match and told Dsis he was coming. We knew what would be coming.
A couple of minutes in, dnephew got the ball and he did it 'come on name, come on name, come on', - really loud, really aggressive in tone, that kind where spit was nearly coming out when he was saying it. He was standing beside me so I immediately said 'stop it, you can't do that'. He went quiet then left after about 15 mins without saying bye to anyone.
I know I did the right thing by the children, he's not helping or encouraging them by using that tone but I feel bloody guilty today.
