An ideal neighbour
We all have some neighbours. Some of us live door to door with others, some have more distant 'company' - particularly these who live in detached houses.
Generally, neighbourhood is seemed to be useful but in some cases it may be really nasty. People sometimes are very inquisitive, especially old women, they might poke their noses into our affairs. Furthermore, youth may be very noisy - they can listen to the music extremely loudly or often give some crazy parties.
We may complain about our noisy, rude or nosy neighbours, but there is no better way of prevent burglars from breaking into your flat than having watchful neighbours. A good, sincere person living around can protect us from theft and disaster (e.g. in danger of fire).
So I think that a nice, kind-hearted neighbour is a treasure. When you are preparing a meal and suddenly it occurs to you that you are lacking in salt or flour, such an ideal person will lend you anything you ask. Moreover, the good neighbour can look after your child for a while, run errands when you are ill. Besides, it's nice just to drop in for a chat to your neighbour or ask for her/his advice.
Therefore, it is worth being on good terms with people around. You have to care about her/him a little and she or he will repay you when you are in need.
