I don’t much like it when elderly couples are characterised as ‘sweet’ or ‘cute’. I think it is patronising and condescending. It ignores the fact that older people are smart, experienced and tough. If they have maintained a relationship for long enough to be growing old together then they are patient, loving and tolerant as well.
This 1930s photobooth photo from the USA shows a couple that has lived well and survived. They appear to be dressed up for a special occasion or simply for a trip into town, which may have been a special occasion itself. They still have a sense of adventure and fun to have stopped, into what was a very recent invention, to have their photo taken. I like their matching granny glasses, her lace collar and beads.
They both have wonderful half smiles that make me feel that they were enjoying themselves and each others company.
