I dont like deleting texts

Am preparing to temporary migrate to my brother's phone.
So I need to uproot everything in my phone to his.
I feel sad because my sim card can't take all the texts with me.
The texts that make me smile, those texts that made my heart skip a beat, those texts that I read and feel so sad.
& I have to delete them all away.
I dont like it.

....
Not one left.
