Everyone can find someone as long as they put some effort into searching and are honest about their status and who would be interested in them.

If I take this as a statement meant to be strictly true, it rings false. It seems very unlikely that people would happen to occur in the proper proportions so that everyone would find someone. At least it seems there would be something like a 50% chance of there being an 'odd man out' even if everything else worked out perfectly.
