Hi, mum and dad!
Sorry I've not written in a while. I haven't been busy or anything, just being a horribly inattentive son (and brother, really, I haven't seen anyone but Ginny and that's only because she's taking my class).
I was thinking of popping by for a visit this weekend to see you both—Mum, don't even think about cutting my hair, but I will let you on the condition you make my favourite stew. Are you two busy? Would you mind if I came over? I might come by anyway, it's not like you can turn me away, right?
