First, you must take the initiative to meet a girl who likes you on the bus. Otherwise, if you accidentally get off at the next stop, we will never find him again. Actually, I've tried this situation before, but I met a boy I like very much while waiting for the bus. Later, I looked for him at school for a long time. If I don't find her, I will definitely miss this person all the time, I will really want to go back to that day, and I will even feel very sorry that I couldn't contact him actively at that time.
Second, there may only be one meeting on the bus, so when we meet someone who has a good impression on us on the bus, we can take the initiative to contact her and get to know her, because the meeting on the bus may only be this time. Even if we take this bus next time, we may not meet him. So you know, some things have only one chance, so we must seize the opportunity. If we want to contact, we should contact directly. Some girls like boys playing straight ball very much, so there is nothing wrong with direct contact at this time.
Third, there will be a story at the beginning. After all, there will be a story at the beginning. No matter whether we end up together or not, at least we know ourselves and have no regrets. Some people will say, don't wait until the next meeting, but I haven't seen this girl since then. So it's better to do it now than next time.
