hi is this a roleplay for adults, young children or teenagers? are you going to have to act out the roleplay?
how about performing two contrasting roleplays.
one where someone has friends and when something happens there are people there to help them and another roleplay where the person has no friends and therefore no 'support network'.
you could include things like the reasons why we all need friends - to look out for each other, to share things with, support, shared experience, advice, etc.
or you could do a short role play about being the 'last man on earth' considering how lonely it would be and all the things we would miss out on.
hope this helps a bit.
