Is it possible to have silly and humorous interactions with people without coming across as stupid?
You can be silly and still be respected but it’s tough. If you get too silly too often people will think you are joking when you are serious. People who act silly are absolutely compelled to do so regardless of the consequences. Maybe you are one of those people but just understand that you do so at the expense of the respect you have so carefully cultivated. Learn to pick your spots and your company. Not drinking will be a plus.
