Feeling ignored

sometimes I feel very ignored by my family, like I was telling them about the really cool set we built in my class for theater since I’m in theater tech and I could tell they just weren’t listening at all and I just walked away and they didn’t even seem to notice and like it just really hurts since they always pay attention to my little siblings and I get that they are little kids and I’m supposed to be “grown” but sometimes I can’t help it but just want a bit of their time still
