My Grandma sent me a text recently, even though she struggles to type what she means accurately (she accidently taps the keys more times than she needs to):
She used to be a code-breaker back in WW2, so she's always enciphering things, I suspect she may be sending me a code of some kind to crack...
What should I send back to her?
Hi Melkor! Just got my new mobile & it's gr8! Could you help me find what computer i should get? or-sw-so-px-ve-te-uk-ud
