Tact (or lack of it)

Nearly 2 years after my cerebellum brain bleed and I am still coming to terms with some of the subtler after-effects. My wife tells me I lack tact now whereas before I was far more sensitive to others.  If I have ever offended you in the past (or do so in the future) I certainly do not intend this. Please accept my most humble apologies and blame it on my brain!
