My girlfriend's new friends

My girlfriend has now become friends with a couple other women who are also amputees. One woman (Lisa) who is in her 50's is missing her lower left arm. The other woman (Susan) is in her late 20's and has had her right leg amputated at the hip. Both women have come over to our house several times this year. Susan is planning her wedding for early next year and my girlfriend and Lisa are helping her.
