What does it mean when a girl doesn't reply to your message for a week and suddenly sends a message asking you to bargain in Pinduoduo one day?

Those who can bargain in the group are people who are slightly closer than ordinary friends, but they are not very familiar. Otherwise, they will call you directly or ask you to do the task on WeChat. Obviously, if you haven't been back for a week, you are not your closest friend. If I can trust you to help me with some personal things, it is a further manifestation of the relationship.
