I still have a pretty good relationship with my parents but it’s usually fairly strained with my mum, and sending a “You’re amazing, Mum” card would seem insincere as she’s often pretty awful to me (and to my sister, but she’s a lot older and more mature than me so just takes a deep breath and deals with it). I used to think it was just a teenage getting-angry-at-your-parents thing and I’d grow out of it but nope, she can be pretty horrible when she wants to be.
