A study revealed that the average American adult has not made a new friend in the last five years.
For many respondents, friendship-making barriers included aversion to the bar scene or the belief that many people already have their friend groups.
Other reasons cited by respondents included commitments to family, with 29 per cent of those surveyed saying it can hinder friendship-building, as well as not having any hobbies where they can meet people, and moving to a new city.
As for adults’ existing number of friends, the average number was 16, according to respondents.
Of the 16, 3 are friends for life, 5 are people that are really liked and would be asked to hang out one-on-one, and 8 are people that they like but would not ask to spend time with one-on-one.
