<human>: Can you summarize the given text in a few sentences?

First Post on TIFU  anyway there is a girl who usually wave's to me and the most of the time I kinda ignore her by thinking she is waving to someone else ,so this time I thought I shouldn't do this anymore a few hours later me and my friend were talking to each other like usual so this girl enters and again she waved towards us and this time me being really sure about it I waved back towards her and said hi and well it turned she was waving to my friend it. And that was really awkward
<bot>: kinda ignored a girl a few times when she is waving towards me making sure not to do so wave back at her later turns out she was greeting someone else
