Elder Arnoczky had a wonderful first week in the MTC. His first companion, Elder Meredith, is from Texas and they both get along great! He mentioned in his first email that he didn't think he would pick up teaching as well and as quickly as he did. Heavenly Father is of course inspiring and watching out for him! His pday is on monday, so that's when we should be hearing from him again!
Also here is his mailing address at the MTC in case you want to write him a letter:
