It’s not absurd to say 20 year olds and 30 year olds are different in that way. From life experience to brain development, it’s a documented fact that older people predate these inexperienced individuals for a variety of reasons. Hence, if you look 20 and a 35 year old is interested in you, I advise you to be cautious. Now, some people will argue that once someone is legally an adult none of that matters. Sure, under the eyes of the law. But you’ve more than admitted here you’re looking for someone immature, that you are also immature. Be careful, older people giving you advice don’t do so to harm you or because they are ashamed they’ve aged. They have often been taken advantage of by older individuals.
