on the flip side i hate when a person despises or ridicules a couple for any form of affection. I mean someone who complains to you about two people 'holding hands too much' and the like. Genuinely upset of simple displays of affection.
I mean 95% of the time i can guarantee you they are single and are a)bitter or b) have always been single and so it usually results from jealousy.
sometimes, but not really, there are peeps that genereally are not affectionate people and are annoyed by any affection shown by others.
