After the funeral service many people hold a "Wake" to remember and generally relieve the tension caused by the recent events. It can be a simple family matter or something arranged by the funeral director.
Some of the options are-

• Cup of tea and a biscuit at a family home
• Cup of tea, sandwiches and some alcohol at a family home
• Refreshments at a local club or function room, alcohol provided or people buy their own

Whatever you do make sure you're comfortable with the arrangements.
