They are going to do things you don’t agree with or do agree with. Sometimes you just have to accept that people aren’t changing like you want them too. Some aren’t maturing like you are, while others are mentally aging in huge strides. Everyone grows up in different ways, some require large mistakes, while others just need a little introspection.
We can’t expect everyone to agree with everyone’s lifestyle and some people have good points on why they don’t agree with someone’s choices. However, you can’t expect someone to throw away where they are going or what they are doing, because it is always their choice.
Everyone is entitled to their own opinion, and you have to be okay with that as long as they aren’t preventing you from something. And you have the right to be how you want to. Either way no one is right or wrong when it comes to opinions.
