Re: Lovey dovey In public
^ Of course, there should not be any discrimination between the rules for elder and younger couples and I did not come across any post stating anything as such that it is ok for older couples to be openly intimate but a crime for younger couples.
As I said earlier, the appropriateness depends on the extent of the act and one's surroundings. People can tolerate the lovey dovey behaviour of couples if done to a reasonable extent and under apposite conditions, but one also has to be considerate of the fact that just because he/she feels comfortable doing something publicly does not mean that the others will too. Hence, one should act accordingly.
Btw, affection and intimacy are not really same, one does not necessarily accompany other, like affection can be shown without being intimate.
As far as the case of 'them having no sharam or izzat' is concerned, I prefer not to comment on these issues. Any particular behaviour can be considered normal by one, immodest by a second, cute by a third person, rude by another and so one. Everyone has a difference of opinions and can have different classifications and definitions of certain things. As far as the topic under consideration is concerned, I don't think just by hugging one's spouse in public makes one less respectable than others. Who knows, the person we might label as being immodest or disreputable based on our standards, is the one highly regarded in the eyes of Allah (swt) for whatever reason.
