You need to tell your mom that you are 13 years old, and at this age, girls are more into music than kids TV shows; so tell her to buy you nicer, puffy and thin clothes. Not jumpers and pink stuff. iCarly isn't really childish. If you saw some of the episodes, they include immature words like - Immature stuff! :3 When the squirrels were fighting, they were actually doing something... else! xD
And slowly tell her this. You are 13. Teenager. Teenagers wear? Young adult clothes.
And so what if she holds your hand? You are still young. You might need to be held on to until your mom can trust you. Maybe she loves you. Here is an idea, hold shopping bags, that way she can't hold your hand. Or just have earphones on, and when she tries to hold your hand, pretend to fix earphones on your ears or something like that. But, don't hurt her feelings.
The Vampire Diaries.
This show is my life. I love Mystic Fall boys. ♥
