Sociologists say on average 30% of people we meet will like us, 30% will dislike us and 30% will be indifferent to us. It doesn't bother me if people dislike me, I'm not going to be everyone's cup of tea am I?
With so many different personalities being developed in life through our many and varied mixes of nature/nurture it stands to reason we're not going to get on with everyone. Don't let it bother you. Avoid unpleasant people wherever possible and forget about them.
