Lilac flowers

Jut found these lovely small flowers in the garden!!:) just between to largish plant pots and the look cool and I've not noticed them before in the garden and another Hot Sunny day in Stowmarket!!! Love this weather but it's a shame I'm at school in lessons most of the day. So I can't enjoy the lovely sunshine , and I don't really like walking home as its too hot too after a busy day at school I just can be Naffed too!! Why do I have to live so far away from the high school!!:(
