I've made rebuses #1-4 below, presumably from easiest to hardest. What phrase is each trying to say? First to solve all four gets the check mark!
#1
Note: the phrases are unrelated.
1 is
LOVE AT FIRST SIGHT
2 is
MIXED FEELINGS
3 is
FALL ON DEAF EARS
4 is
NOT SO FAST (Not Sofa St.)
1 is obviously
LOVE AT FIRST SIGHT
2 is (thanks @Rand al'Thor)
MIXED FEELINGS
3 is to
FALL ON DEAF EARS
4 I'm unsure, but the rest I'm confident of.
Solution to #2 is
MIXED FEELINGS.
Solution to #1 might be
THIRD WHEEL, although I'm not convinced.
1.
cross my heart (crosshair over a heart)
2.
mixed feelings (word "feelings" mixed up)
3.
Afraid of falls (afraid-Duff under pictures of Fall)
4.
unsituated (un-seat-way-dot)
My guess for #4
NOT SO FAR OUT (NOT+SOFA+ROUT(E), dot acts like a comma, meaning "remove last letter of the word").
