Jealousy in its various forms is especially likely to arise between brothers, and between sisters also for the same reason, which is that comparisons are constantly suggested and even made with injudicious openness by parents and teachers, and by talkative friends. The development of the faculties in youth is always extremely interesting, and is a constant subject of observation and speculation. If it is interesting to on-lookers, it is still more likely to be so to the young persons most concerned. They feel as young race-horses might be expected to feel towards each other if they could understand the conversations of trainers, stud-owners, and grooms. If a full account of family life could be generally accessible, if we could read autobiographies written by the several members of the same family, giving a sincere and independent account of their own youth, it would probably be found in most cases that jealousies were easily discoverable. They need not be very intense to create a slight fissure of separation that may be slowly widened afterwards. If you listen attentively to the conversation of brothers about brothers, of sisters about sisters, you will probably detect such little jealousies without difficulty. "My sister," said a lady in my hearing, "was very much admired when she was young, _but she aged prematurely_." Behind this it was easy to read the comparison with self, with a constitution less attractive to others but more robust and durable, and there was a faint reverberation of girlish jealousy about attentions paid forty years before. The jealousies of youth are too natural to deserve any serious blame, but they may be a beginning of future coolness. A boy will seem to praise the talents of his brother with the purpose of implying that the facilities given by such talents make industry almost superfluous, whilst his own more strenuous efforts are not appreciated as they deserve. Instead of soothing and calming these natural jealousies some parents irritate and inflame them. They make wounding remarks that produce evil in after years. I have seen a sensitive boy wince under cutting sarcasms that he will remember till his hair is gray.
