So I got a new to me motorcycle yesterday and it was pointed out to me that I can get super excited over things like the bike but 90% of the time I'm very meh. They gave me examples of how people will ask me to go do things I do genuinely enjoy but my responses will be like "yeah that sounds good" or "sure" like I'm unenthusiastic (atleast in their eyes, and in my exes eyes although she didn't explain it to me in a way I understood until yesterday aka 2 years later). I'm not trying to be meh it's just hard to get me so excited i start getting goofy. If i dont want to go do something I'll say as much, so for me saying a simple yes is expressing genuine interest but apparently it dosent come off that way. Is it a problem that I'm ussualy that laid back about things? If so how do I fix it without making it seem forced.
Edit: ì would like to add I'm not always so mellow like I will get just as goofy and hyper if I see my favorite person after a long day of work and stuff like that it's just not the norm for me
