My boyfriend has a summer car, an 80's mustang that he is just in love with. He has had it for quite a few years, and has fixed it up, etc. He is a car guy at heart. He is 25 years old, and it seriously makes this huge smile cross his face when he finally gets to drive it in the warmer weather. Thing is, i don't like it very much, and it bothers me that he has to rev it infront of everyone and speeds off a light all the time. I feel like telling him he's being childish but I dont want to be mean. I just feel like he think it makes him seem cool...it bugs me to no end. What can I tell him or am I being unreasonable? I'm glad he's happy, but can't he just keep it down a bit or grow up a little?! I know this sounds harsh, its just that he thinks it makes him more of a man or something when really it makes me cringe.
