text: how long should you wait on someone who asked you to do something? this lady at school asked me to help her move. told me to meet her at school at 930am. i was there at 920am. she never showed. i waited until 1012am. thats 40 minutes. was that a fair amount of time to wait? too long? too short?? whats the etiquette when you are the one being asked to meet someone? if someone who you offer to help makes you wait longer than 10 minutes, it is to long on your part. what respect do they have for you as a friend for offering?
