Btw I Use They/Them Im Just Closeted With My Openly Transphobic, Religion Hating And Not As Obviously Homophobic (he laces it into his words) Dad And My Transphobic (the same way my dad is with his homophobia) Mum So I Use He/Him Around Them 1: I Couldnt Find My Fathers Day Card 4 My Dad (it was today actually, one day before fathers day) And I Hadn't Filled It In (well i lost it so how could i of? cause my mum bought it ages ago for me cause she was going onto crutches (she is on crutches at the time of this) She Was Pissed Of At Me For Not Having It (understandable but not to the degree she was) I Told Her I Was Gonna Look Again In A Bit (i was looking for it for a good 30 min and decided to take a 10 min break) Then She Decided To Find It Herself Cause " i wont bother cause i dont do anything " (most bullshit ive ever heard in my life) Then She Found It And Then Threw It Onto My Bed And Had A Tantrum, I Told Her To Calm Down (cause she was just livid some how) Then she Was Like " CALM DOWN? IM ON CRUTCHES AND I HAD TO FIND IT FOR YOU " (which i never even asked her too) Then She Screamed And Argued With Me Cause I " Didnt Give A Shit " And " Didnt Care About Anything " And Then Went On Yapping About " Everything Is GIVEN To You " (like tf u mean it isnt at all girl and anyways thats your parenting style and you can change that) I Proceeded To Tell Her " Then Don't " And Then She Had A Tantrum, Left The Room And Slammed The Door 2: I Forgot To Fill The Fridge With Some (of my) Dr Pepper Cans (keep in mind these are mine and no clue why she cares) And She Had A Full On Argument With Me About This 3: Forgot To Feed The Cats (this was only 20 min later than usual, whenever the fuck that is she keeps changing the usual from 5PM to 5:30PM to 6PM whenever she wants) And She Was Like " Your STARVVVINNNGG Them " And Was Saying To My Cats (yk in that really shitty voice that all mums have) " he doesnt want to feed you does he " "he doesnt care about you" "awwww do you want food is he refusing to feed you??? " and yeah i fed them and then she started the " do you even want them " bullshit she does
