This probably feels all rather familiar – think again about your neighbourhood or club and being able to rely upon the people making up those communities for help.
Mae’n siŵr bod hyn yn teimlo’n eithaf cyfarwydd - meddyliwch eto am eich cymdogaeth neu glwb, a’ch gallu i ddibynnu ar y bobl sy’n ffurfio’r cymunedau hynny, am gymorth.
