"As you can see it’s Pensieve night. You will find a private Pensieve in each of your rooms if you wish to enjoy the experience privately however this one here is for group viewing. Each Pensieve is ensorceled to only allow memories involving club members. We do not want to get drawn into a lawsuit. We would request that this communal vessel be used only to share memories from within the club unless you have the ability to ask permission from the other party. We do realise that some people have figured out true identities at this point, but we recognise this information is still sacrosanct to some people, so play carefully."
