The first time I went to Dublin, I brought back souvenirs for family and friends. I remember that for my dad, I bought a Guinness mug, like this one.
My dad didn’t really have much use for it, so it sat in the cupboard for a while, unused. At some point I adopted it for my own – I can’t remember whether this happened while I was still living with my parents, or when I moved out, or whether I actually claimed it during a visit to their house after I had already moved out.
For many years, it has been my “office” mug, and has contained maybe 1000 cups of tea or coffee per annum.
This was an utterly pointless anecdote.
