Break up into working parties of 6 or more people to help the elderly or a young family in your congregation or district.
Select families/individuals who accept your help. Allocate 2 people on ‘sandwich making’ duty at your church hall/space (you could end up with 20 people making sandwiches and filling cordial bottles or thermos, if you have 10 groups!). The remaining 4 people head off and work on blitzing someone’s backyard! When lunch arrives, sit with the family or elderly person and enjoy a picnic at lunchtime to give everyone enough energy to finish the job that was started!
