I have just realized the letter i sent was quite a big letter, i put 2 1st class royal mail stamps on them and only 1 st on the letter return, do you think this is the reason it's taken 18 days or do you think it still might turn up?

Ahh thanks man i was getting worried, you have supplied me with more patients. I would honestly marry Sophie if i could haha :')

I sent a Letter and a Photo on the 23rd of May, It's been 18 days, do you think it will return :'(
