why is everything such a pain? almost everything. Okay so I rly wanted to go somewhere tonight but a couple months ago I accepted an invite from this lady and tonight she will be there and will want to give me a ride home ( she is rly insistant) and i dont want her to take my home cuz i dont want her to know where i moved and last time she drove me to the station cuz luckily i was going somewhere after so I dont know what to do. Idf i dont leave like in 10 minutes well 5 i will be late so no point of going at all - i am so mad cuz my planw as t ttell her its ok i am fine i iwll get there on my own which i could still and the only reason i took the ride to the station last time was cuz i was ina rush although i dunno but yah..... so should i go and say its ok i always take the trains/busses late anyways or should i just not go and my frend who will be there and will be so sad. at mee.
