You offer to teach Jennie a few basics of cooking. Jennie is delighted.
Everyone else is doing the same, offering to help one another. Sarah is delighted that the group is benefiting from the meeting today.
You arrange to meet Jennie at her house. You arrive at her house the next day and spend a great morning baking a cake and cooking an omelette for lunch. Jennie is clearly enjoying herself and mentions that she’ll be the envy of all her friends. None of them are any better at cooking than Jennie!
