I (24f) was primarily in the custody of my dad when i was a child. Dispite that i still have a great relationship with my half siblings (I only say half here to make the relation clear, my sibling are sibling dispite labels like half or step).
My brother (17m) and I are really close. He comes to me with problems, secrets and for advice. For a while now hes had a mess of facial hair. Hes never shaved it since his dad has never bothered to teach him. The one time he tried he cut himself badly and hasnt tried since.
Yesterday he was at my place, he talked to me about how hes going to hang out with a boy he likes the next day but is self concious about his messy facial hair. I thought since my step dad isnt bothering to teach him I will. I shave my body and have helped exs shave their face so I know what im doing lol.
I taught him how to trim it then shape it for when he wants to keep it then taught him how to shave it by helping him shaving it all off. He was greatful and it helped him get over the nerves of cutting himself.
When he went home he was pretty excited about it and showed mum how he shaved his face and how i helped him. Mum and especially step dad are now extreamly pissed because i took that bonding moment away from him. I call bs since his had facial hair since 13 and his dad still hasnt bothered to teach him. AITA?
