I can fix a punctured tire now!!

I have had a hard time more than a week due to my new bike.
it was punctured on the way to work. It costs 10euro to fix it at a bike shop.
10euro.... it is quite small money as usual but here is Ireland and I am making too low(?) money. So I don't wanna spend money to fix a tire. I spent more than 10euro... consequently... haha...
I asked my flatmate Ernesto how to fix it and bought a inner tube and a pump.
I thought it would be fine but of course it didn't. If that stuff would be fine at first , I would have not gotten too much stress.
I changed tube again and again and also put the tube into water to find a puncture.
Whenever I believe this time is a success! They laughed at me.... so stress!!!!!!
I was mad at a seller who I bought the bike. I am so sorry to him. that was caused from my ignorance... haa....
finally I found a tiny needle putting on the bike. That's why chaning a tube was no use...
I cleaned the needle and patched on the puncture with a band that we usually use when we are cut
Now.... I know most tips of changing a tube!
Hoooa.......
It so.......satisfy...?? or not....?
fine... good ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ
