Goatees were great back when you started yours...the sign of a non-conformist, and slightly dangerous. Now every other guy seems to have one.
Not to mention that it has more grey than brown in it....
I have a dear old friend (for more than 50 years!) who is the leading indicator of the death of a fashion trend. He’s always been the last to adopt.....Italian horn necklace, gold chain, sideburns, mullett, tattoo, etc....and about six months ago: shaved head and goatee. Over! (I hope he starts wearing mansandals soon!)
