//we’ve all got family that we can only see from a distance and not hug etc so I think that’s why it’s upset people so much .//
"Social Distancing" (or anti-social distancing as I prefer to call it) is guidance, not a rule and is not included in any legislation. It is advisory. If you and those you want to hug are happy to do so (wherever you happen to be) just go right ahead and do it.
The government has succeeded in constructing a compliant population by confusing them between "rules" and "advice." It constantly makes reference to the "two metre rule"; it says that you can do this or that "subject to the two metre rule". It isn't a rule; it's not illegal to approach somebody closer than that and it's not illegal to give them a hug or a kiss (so long as you both agree, naturally).
It's worse than that. Many people are of the belief that they are not allowed to use public transport unless they are a "key worker" or their journey is "essential". Once again they are wrong. Public transport is for anybody for any purpose. The only legislation specific to it is that you must wear a face covering when either boarding it or travelling on it (but not whilst you're on the station - except for TfL controlled services). The only restrictions on your movements currently are that you must not gather in groups of more than six outdoors and you must not enter another person's house unless you have formed a "link" with their household (and you and they can then have no other "links").
So get out there, give your family a hug if they agree to it, go for a bus ride, go for a train ride. The country needs to break out of the government-induced torpor it has descended into.
